[PATCH net 0/3] bnxt_en: Bug fixes

[Michael Chan]

[-- Attachment #1: Type: text/plain, Size: 604 bytes --]

This patch series includes 3 fixes:

1. Fix an occasional VF open failure.
2. Fix a PTP spinlock usage before initialization
3. Fix unnecesary RX packet drops under high TX traffic load. 

Michael Chan (2):
  bnxt_en: Initiallize bp->ptp_lock first before using it
  bnxt_en: Fix unnecessary dropping of RX packets

Somnath Kotur (1):
  bnxt_en: Fix possible bnxt_open() failure caused by wrong RFS flag

[PATCH net 1/3] bnxt_en: Fix possible bnxt_open() failure caused by wrong RFS flag

[Michael Chan]

[-- Attachment #1: Type: text/plain, Size: 2445 bytes --]

From: Somnath Kotur <somnath.kotur@broadcom.com>

bnxt_open() can fail in this code path, especially on a VF when
it fails to reserve default rings:

bnxt_open()
  __bnxt_open_nic()
    bnxt_clear_int_mode()
    bnxt_init_dflt_ring_mode()

RX rings would be set to 0 when we hit this error path.

It is possible for a subsequent bnxt_open() call to potentially succeed
with a code path like this:

bnxt_open()
  bnxt_hwrm_if_change()
    bnxt_fw_init_one()
      bnxt_fw_init_one_p3()
        bnxt_set_dflt_rfs()
          bnxt_rfs_capable()
            bnxt_hwrm_reserve_rings()

On older chips, RFS is capable if we can reserve the number of vnics that
is equal to RX rings + 1.  But since RX rings is still set to 0 in this
code path, we may mistakenly think that RFS is supported for 0 RX rings.

Later, when the default RX rings are reserved and we try to enable
RFS, it would fail and cause bnxt_open() to fail unnecessarily.

We fix this in 2 places.  bnxt_rfs_capable() will always return false if
RX rings is not yet set.  bnxt_init_dflt_ring_mode() will call
bnxt_set_dflt_rfs() which will always clear the RFS flags if RFS is not
supported.

[PATCH net 2/3] bnxt_en: Initiallize bp->ptp_lock first before using it

[Michael Chan]

[-- Attachment #1: Type: text/plain, Size: 1825 bytes --]

bnxt_ptp_init() calls bnxt_ptp_init_rtc() which will acquire the ptp_lock
spinlock.  The spinlock is not initialized until later.  Move the
bnxt_ptp_init_rtc() call after the spinlock is initialized.

[PATCH net 3/3] bnxt_en: Fix unnecessary dropping of RX packets

[Michael Chan]

[-- Attachment #1: Type: text/plain, Size: 1599 bytes --]

In bnxt_poll_p5(), we first check cpr->has_more_work.  If it is true,
we are in NAPI polling mode and we will call __bnxt_poll_cqs() to
continue polling.  It is possible to exhanust the budget again when
__bnxt_poll_cqs() returns.

We then enter the main while loop to check for new entries in the NQ.
If we had previously exhausted the NAPI budget, we may call
__bnxt_poll_work() to process an RX entry with zero budget.  This will
cause packets to be dropped unnecessarily, thinking that we are in the
netpoll path.  Fix it by breaking out of the while loop if we need
to process an RX NQ entry with no budget left.  We will then exit
NAPI and stay in polling mode.

Fixes: 389a877a3b20 ("bnxt_en: Process the NQ under NAPI continuous polling.")

But there is a dependency on patch #2 though.  So #2 needs to be queued as well.

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

This short series fixes resource related logic in the driver, mostly

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

[Michael Chan]

3 bug fixes related to XDP ring accounting in bnxt_setup_tc(), freeing
MSIX vectors when bnxt_re unregisters, and preserving the user-administered
PF MAC address when disabling SRIOV.

Michael Chan (3):
  bnxt_en: Fix .ndo_setup_tc() to include XDP rings.
  bnxt_en: Free MSIX vectors when unregistering the device from bnxt_re.
  bnxt_en: Do not setup MAC address in bnxt_hwrm_func_qcaps().

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]

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.
