bnxt: min_mtu 60, max_mtu 9000
bnx2x: min_mtu 46, max_mtu 9600
- Fix up ETH_OVREHEAD -> ETH_OVERHEAD while we're in here, remove
duplicated defines from bnx2x_link.c.
bnx2: min_mtu 46, max_mtu 9000
- Use more standard ETH_* defines while we're at it.
bcm63xx_enet: min_mtu 46, max_mtu 2028
- compute_hw_mtu was made largely pointless, and thus merged back into
bcm_enet_change_mtu.

we have two processes to do:
P1#: ifconfig eth0 down; which will call bnx2_close, then will
, and set Null to stats_blk
P2#: ifconfig eth0; which will call bnx2_get_stats64, it will
use stats_blk.
In one case:
--P1#-- --P2#--
stats_blk(no null)
bnx2_free_mem
->bp->stats_blk = NULL
GET_64BIT_NET_STATS
then it will cause 'NULL Pointer' Problem.
it is as well with 'ethtool -S ethx'.
Allocate the statistics block at probe time so that this problem is
impossible

The pci shutdown handler added in:
bnx2: Add pci shutdown handler
commit 25bfb1dd4b
created a shutdown down sequence without chip reset if the device was
never brought up. This can cause the firmware to shutdown the PHY
prematurely and cause MMIO read cycles to be unresponsive. On some
systems, it may generate NMI in the bnx2's pci shutdown handler.
The fix is to tell the firmware not to shutdown the PHY if there was
no prior chip reset.

Auto-mdix currently only works if autoneg is enabled. This patch enables
auto-mdix all the time by setting a bit in a PHY register. Define
meaningful constants for this PHY registers.

Instead of using symbol_get(), cnic can now directly call the cnic_probe
functions in struct bnx2x and struct bnx2. symbol_get() is not reliable
as it fails when the module is still initializing.

with BNX2_ prefix for namespace consistency. Currently, these macro names
conflict with similar macros in bnx2x.h, preventing the cnic driver from
including both bnx2.h and bnx2x.h. Including bnx2x.h in cnic.c will remove
many redundant definitions and simplify the interface.

This is very similar to bnx2x conversion, but bnx2 only requires 16bytes
alignement at start of the received frame to store its l2_fhdr, so goal
was not to reduce skb truesize (in fact it should not change after this
patch)
Using build_skb() reduces cache line misses in the driver, since we
use cache hot skb instead of cold ones. Number of in-flight sk_buff
structures is lower, they are more likely recycled in SLUB caches
while still hot.

The split-up generated a trivial conflict with removal of a
stale reference to Documentation/networking/net-modules.txt.
Remove it from the new location instead.
- fs/sysfs/dir.c:
Fairly nasty conflicts with the sysfs rb-tree usage, conflicting
with Eric Biederman's changes for tagged directories.
Moves the drivers for Broadcom devices into
drivers/net/ethernet/broadcom/ and the necessary Kconfig and Makefile
