mv88e6xxx fixes (mainly 88E6393X family)
sending v2 of these fixes.
Original cover letter:
So I managed to discovered how to fix inband AN for 2500base-x mode on
88E6393x (Amethyst) family.
This series fixes application of erratum 4.8, adds fix for erratum 5.2,
adds support for completely disablign SerDes receiver / transmitter,
fixes inband AN for 2500base-x mode by using 1000base-x mode and simply
changing frequeny to 3.125 GHz, all this for 88E6393X.
The last commit fixes linking when link partner has AN disabled and the
device invokes the AN bypass feature. Currently we fail to link in this
case.
Changes since v1:
- fixed wrong operator in patch 3 (thanks Russell)
- added more comments about why BMCR_ANENABLE is used in patch 6 (thanks
Russell)
- updated some return statements from
if (something)
return func();
return 0;
to
if (something)
err = func();
return err;
(err is set to 0 before the condition)

Function mv88e6xxx_serdes_pcs_get_state() currently does not report link
up if AN is enabled, Link bit is set, but Speed and Duplex Resolved bit
is not set, which testing shows is the case for when auto-negotiation
was bypassed (we have AN enabled but link partner does not).
An example of such link partner is Marvell 88X3310 PHY, when put into
the mode where host interface changes between 10gbase-r, 5gbase-r,
2500base-x and sgmii according to copper speed. The 88X3310 does not
enable AN in 2500base-x, and so SerDes on mv88e6xxx currently does not
link with it.
Fix this.

Inband AN is broken on Amethyst in 2500base-x mode when set by standard
mechanism (via cmode).
(There probably is some weird setting done by default in the switch for
this mode that make it cycle in some state or something, because when
the peer is the mvneta controller, it receives link change interrupts
every ~0.3ms, but the link is always down.)
Get around this by configuring the PCS mode to 1000base-x (where inband
AN works), and then changing the SerDes frequency while SerDes
transmitter and receiver are disabled, before enabling SerDes PHY. After
disabling SerDes PHY, change the PCS mode back to 2500base-x, to avoid
confusing the device (if we leave it at 1000base-x PCS mode but with
different frequency, and then change cmode to sgmii, the device won't
change the frequency because it thinks it already has the correct one).
The register which changes the frequency is undocumented. I discovered
it by going through all registers in the ranges 4.f000-4.f100 and
1e.8000-1e.8200 for all SerDes cmodes (sgmii, 1000base-x, 2500base-x,
5gbase-r, 10gbase-r, usxgmii) and filtering out registers that didn't
make sense (the value was the same for modes which have different
frequency). The result of this was:
reg sgmii 1000base-x 2500base-x 5gbase-r 10gbase-r usxgmii
04.f002 005b 0058 0059 005c 005d 005f
04.f076 3000 0000 1000 4000 5000 7000
04.f07c 0950 0950 1850 0550 0150 0150
1e.8000 0059 0059 0058 0055 0051 0051
1e.8140 0e20 0e20 0e28 0e21 0e42 0e42
Register 04.f002 is the documented Port Operational Confiuration
register, it's last 3 bits select PCS type, so changing this register
also changes the frequency to the appropriate value.
Registers 04.f076 and 04.f07c are not writable.
Undocumented register 1e.8000 was the one: changing bits 3:0 from 9 to 8
changed SerDes frequency to 3.125 GHz, while leaving the value of PCS
mode in register 04.f002.2:0 at 1000base-x. Inband autonegotiation
started working correctly.
(I didn't try anything with register 1e.8140 since 1e.8000 solved the
problem.)
Since I don't have documentation for this register 1e.8000.3:0, I am
using the constants without names, but my hypothesis is that this
register selects PHY frequency. If in the future I have access to an
oscilloscope able to handle these frequencies, I will try to test this
hypothesis.

Always use MLX5_FLOW_TABLE_OTHER_VPORT flag when creating egress ACL

which is filled in the flow table creation command but as the

Transport Interface Receive (TIR) objects perform the packet processing and
reassembly and is also responsible for demultiplexing the packets into the
different RQs.
There are certain TIR context attributes that propagate to the pointed RQs
and applied to them (like packet_merge offloads (LRO/SHAMPO) and
tunneled_offload_en). When TIRs do not agree on attributes values, a "last
one wins" policy is applied. Hence, if not synced properly, a race between
TIR params update and a concurrent TIR create/modify operation might yield
to a mismatch between the shadow parameters in SW and the actual applied
state of the RQs in HW.
tunneled_offload_en is a fixed attribute per profile, while packet merge
offload state might be toggled and get out-of-sync. When this happens,
packet_merge offload might be working although not requested, or the
opposite.
All updates to packet_merge state and all create/modify operations of
regular redirection/steering TIRs are done under the same priv->state_lock,
so they do not run in parallel, and no race is possible.
However, there are other kind of TIRs (acceleration offloads TIRs, like TLS
TIRs) which are created on demand for each new connection without holding
the coarse priv->state_lock, hence might race.
Fix this by synchronizing all packet_merge state reads and writes against
all TIR create/modify operations. Include the modify operations of the
regular redirection steering TIRs under the new lock, for better code
layering and division of responsibilities.

The change of VF state is visible in dmesg now.

is not logged in dmesg.

Enabling the XDP bpf_prog access to data_meta area is a very small
change. Hint passing 'true' to xdp_prepare_buff().
The SKB layers can also access data_meta area, which required more
driver changes to support. Reviewers, notice the igc driver have two
different functions that can create SKBs, depending on driver config.
Hint for testers, ethtool priv-flags legacy-rx enables
the function igc_construct_skb()
ethtool --set-priv-flags DEV legacy-rx on

Driver already implicitly supports XDP metadata access in AF_XDP
zero-copy mode, as xsk_buff_pool's xp_alloc() naturally set xdp_buff
data_meta equal data.
This works fine for XDP and AF_XDP, but if a BPF-prog adjust via
bpf_xdp_adjust_meta() and choose to call XDP_PASS, then igc function
igc_construct_skb_zc() will construct an invalid SKB packet. The
function correctly include the xdp->data_meta area in the memcpy, but
forgot to pull header to take metasize into account.

avic_set_running() passes the current CPU to avic_vcpu_load(), albeit
via vcpu->cpu rather than smp_processor_id(). If the thread is migrated
while avic_set_running runs, the call to avic_vcpu_load() can use a stale
value for the processor id. Avoid this by blocking preemption over the
entire execution of avic_set_running().

Volodymyr Mytnyk says:
====================
net: prestera: acl: migrate to new vTcam/counter api
This patch series aims to use new vTcam and Counter API
provided by latest fw version. The advantage of using
this API is the following:
- provides a way to have a rule with desired Tcam size (improves
Tcam memory utilization).
- batch support for acl counters gathering (improves performance)
- gives more control over HW ACL engine (actions/matches/bindings)
to be able to support more features in the future driver
versions
Note: the feature set left the same as was before this patch.
