bnx2x: Fix invalid memory access in rss hash config path.

2018-07-24T23:33:02+00:00

Rx hash/filter table configuration uses rss_conf_obj to configure filters
in the hardware. This object is initialized only when the interface is
brought up.
This patch adds driver changes to configure rss params only when the device
is in opened state. In port disabled case, the config will be cached in the
driver structure which will be applied in the successive load path.

Please consider applying it to 'net' branch.

net: systemport: Fix CRC forwarding check for SYSTEMPORT Lite

2018-07-12T21:47:47+00:00

SYSTEMPORT Lite reversed the logic compared to SYSTEMPORT, the
GIB_FCS_STRIP bit is set when the Ethernet FCS is stripped, and that bit
is not set by default. Fix the logic such that we properly check whether
that bit is set or not and we don't forward an extra 4 bytes to the
network stack.

bnxt_en: Fix for system hang if request_irq fails

2018-07-09T23:27:14+00:00

Fix bug in the error code path when bnxt_request_irq() returns failure.
bnxt_disable_napi() should not be called in this error path because
NAPI has not been enabled yet.

bnxt_en: Do not modify max IRQ count after RDMA driver requests/frees IRQs.

2018-07-09T23:27:14+00:00

Calling bnxt_set_max_func_irqs() to modify the max IRQ count requested or
freed by the RDMA driver is flawed.  The max IRQ count is checked when
re-initializing the IRQ vectors and this can happen multiple times
during ifup or ethtool -L.  If the max IRQ is reduced and the RDMA
driver is operational, we may not initailize IRQs correctly.  This
problem shows up on VFs with very small number of MSIX.

There is no other logic that relies on the IRQ count excluding the ones
used by RDMA.  So we fix it by just removing the call to subtract or
add the IRQs used by RDMA.

bnxt_en: Support clearing of the IFF_BROADCAST flag.

2018-07-09T23:27:14+00:00

Currently, the driver assumes IFF_BROADCAST is always set and always sets
the broadcast filter.  Modify the code to set or clear the broadcast
filter according to the IFF_BROADCAST flag.

bnxt_en: Always set output parameters in bnxt_get_max_rings().

2018-07-09T23:27:14+00:00

The current code returns -ENOMEM and does not bother to set the output
parameters to 0 when no rings are available.  Some callers, such as
bnxt_get_channels() will display garbage ring numbers when that happens.
Fix it by always setting the output parameters.

bnxt_en: Fix inconsistent BNXT_FLAG_AGG_RINGS logic.

2018-07-09T23:27:14+00:00

If there aren't enough RX rings available, the driver will attempt to
use a single RX ring without the aggregation ring.  If that also
fails, the BNXT_FLAG_AGG_RINGS flag is cleared but the other ring
parameters are not set consistently to reflect that.  If more RX
rings become available at the next open, the RX rings will be in
an inconsistent state and may crash when freeing the RX rings.

Fix it by restoring the BNXT_FLAG_AGG_RINGS if not enough RX rings are
available to run without aggregation rings.

bnxt_en: Fix the vlan_tci exact match check.

2018-07-09T23:27:14+00:00

It is possible that OVS may set don’t care for DEI/CFI bit in
vlan_tci mask. Hence, checking for vlan_tci exact match will endup
in a vlan flow rejection.

This patch fixes the problem by checking for vlan_pcp and vid
separately, instead of checking for the entire vlan_tci.
