In my patch c194992cbe ("skge: fix

new mapping (not old) was passed to pci_unmap_single.
If we enable CONFIG_DMA_API_DEBUG, it results in this warning:
WARNING: CPU: 0 PID: 0 at lib/dma-debug.c:986 check_sync+0x4c4/0x580()

not allocated [device address=0x000000023a0096c0] [size=1536 bytes]
This patch makes the skge driver pass the correct value to
pci_unmap_single and fixes the warning. It copies the old descriptor to
on-stack variable "ee" and unmaps it if mapping of the new descriptor
succeeded.
This patch should be backported to 3.11-stable.

During flows which mask block attentions (e.g., register dump) all parities
are masked. However, unlike other blocks the MCP's attention is not masked
inside the block but rather the indication to the driver. If another attention
(e.g., link change) will occour while there's an MCP parity, the driver will
ignore the fact that the parity is masked and erroneously report a parity.
This patch forces the driver to read the MCP masking while checking for
parities.

commit 104a43edb2
cnic: Use CHIP_NUM macros from bnx2x.h
changed the code to use the bnx2x macro NO_FCOE() to determine if FCoE
is supported or not. There is another place in cnic that is still using
the old method to determine if FCoE is supported or not. The 2 methods
may not yield the same result after the network interface is brought down
and up. This will cause the crash as cnic_bnx2x_service_kcq() will access
the uninitialized cp->kcq2.
The fix is to consistently use the same macro CNIC_SUPPORTS_FCOE() which
uses the bnx2x NO_FCOE() macro. As a follow-up, we can clean up the code
to remove the old method as it is no longer needed.
