[PATCH net 0/3] bnxt_en: Bug fixes.

[Michael Chan]

3 bug fixes in this series.  Fix a crash in bnxt_get_stats64() that can
happen if the device is closing and freeing the statistics block at the
same time.  The 2nd one fixes ethtool -L failing when changing from
combined to non-combined mode or vice versa.  The last one fixes SRIOV
failure on big-endian systems because we were setting a bitmap wrong in
a firmware message.

Michael Chan (3):
  bnxt_en: Fix race conditions in .ndo_get_stats64().
  bnxt_en: Fix bug in ethtool -L.
  bnxt_en: Fix SRIOV on big-endian architecture.

[PATCH net 1/3] bnxt_en: Fix race conditions in .ndo_get_stats64().

[Michael Chan]

.ndo_get_stats64() may not be protected by RTNL and can race with
.ndo_stop() or other ethtool operations that can free the statistics
memory.  Fix it by setting a new flag BNXT_STATE_READ_STATS and then
proceeding to read statistics memory only if the state is OPEN.  The
close path that frees the memory clears the OPEN state and then waits
for the BNXT_STATE_READ_STATS to clear before proceeding to free the
statistics memory.

[PATCH net 2/3] bnxt_en: Fix bug in ethtool -L.

[Michael Chan]

When changing channels from combined to rx/tx or vice versa, the code
uses the wrong "sh" parameter to determine if we are reserving rings
for shared or non-shared mode.  It should be using the ethtool requested
"sh" parameter instead of the current "sh" parameter.

Fix it by passing the "sh" parameter to bnxt_reserve_rings().  For
ethtool, we will pass in the requested "sh" parameter.

Fixes: 391be5c27364 ("bnxt_en: Implement new scheme to reserve tx rings.")

[PATCH net 3/3] bnxt_en: Fix SRIOV on big-endian architecture.

[Michael Chan]

The PF driver sets up a list of firmware commands from the VF driver that
needs to be forwarded to the PF for approval.  This list is a 256-bit
bitmap.  The code that sets up the bitmap falls apart on big-endian
architecture.  __set_bit() does not work because it operates on long types
whereas the firmware interface is defined in u32 types, causing bits in
the wrong 32-bit word to be set.

Fix it by setting the proper bits on an array of u32.

Fixes: de68f5de5651 ("bnxt_en: Fix bitmap declaration to work on 32-bit arches.")

Series applied, thanks Michael.

We really should look into generically taking care of the ->ndo_close()
vs. statistics pulling synchronization so that every driver doesn't
need to have code like this.

[PATCH net 0/3] bnxt_en: Bug fixes

[Michael Chan]

Thie first patch fixes a crash during PCIe AER when the bnxt_re RoCE
driver is loaded.  The second patch is a refactor patch needed by
patch 3.  Patch 3 fixes a packet drop issue if queue restart is done
on a ring belonging to a non-default RSS context.  Patch 2 and 3 are
version 2 that has addressed the v1 issue by reducing the scope of
the traffic disruptions:

[PATCH net 0/3] bnxt_en: Bug fixes

[Michael Chan]

This patchset includes 3 small bug fixes to reinitialize PHY capabilities
after firmware reset, setup the chip's internal TQM fastpath ring
backing memory properly for RoCE traffic, and to free ethtool related
memory if driver probe fails.

Rukhsana Ansari (1):
  bnxt_en: Fix TQM fastpath ring backing store computation

Somnath Kotur (1):
  bnxt_en: Call bnxt_ethtool_free() in bnxt_init_one() error path
