[dpdk-dev] [PATCH 3/6] net/bnx2x: fix ramrod timeout

[Rasesh Mody]

From: Shahed Shaikh <shshaikh@marvell.com>

There is a race condition while processing RAMROD
completion in fast path queue through interrupt handler
and polling method.

Interrupt handler invoked from actual interrupt event
and from RAMROD processing polling flow may create a
situation where one flow will read and clear a fastpath
interrupt without actually processing the RAMROD completion.
Thus, causing a RAMROD timeout even though HW sent an
completion event.

Fix this by introducing an atomic variable which will be
set only when interrupt handler needs to process RAMROD
completion.

[dpdk-dev] [PATCH 4/6] net/bnx2x: fix DMAE timeout

[Rasesh Mody]

From: Shahed Shaikh <shshaikh@marvell.com>

In some cases, DPKD application may send packets
while PMD is going through load or unload flow.
This causes firmware to access invalid/unallocated
memory to process transmit buffer. Which results in
error on PCI bus and chip further blocks access to host,
causing a DMAE timeout.

Fix this issue by installing dummy empty transmit and receive
handlers at the beginning of unload path (rte_eth_dev_stop())
and install actual transmit and receive handlers after successful
load of the PMD port (rte_eth_dev_start()). This way, application
won't be able to send packets while device is going through
load/unload flow.

[dpdk-dev] [PATCH 5/6] net/bnx2x: fix race for periodic flags

[Rasesh Mody]

The periodic callout function and the interrupt handler both modify the
periodic flags. There is a possible race condition when an application is
going through dev_stop()/dev_start() and an interrupt handler is invoked.
We also need to ensure that periodic polling is not invoked in interrupt
context.

This patch handles such case by using separate variable to check for
interrupt context. Also, atomically load and store the periodic flag
value.

[dpdk-dev] [PATCH 6/6] net/bnx2x: fix optic module verification

[Rasesh Mody]

Enable the optic module vendor and part number verification from driver
by setting appropriate flags. Link handling module in conjunction with
FW performs optic module verification.

Without this fix the SFP is powered down and the link doesn't come up,
if module verification is enforced in nvram setting.
