[dpdk-dev] [PATCH 01/10] net/bnxt: handle flow create failure

[Kalesh A P]

From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>

If flow create fails due to not enough filter resources,
driver does not populate the rte_flow_error using
rte_flow_error_set().

Since "rte_errno" could have garbage value and is not relaiable,
it could cause a segfault in the stack in port_flow_complain().

Fix it to set rte_flow_error using rte_flow_error_set()
when flow create fails due to not enough filter resources.

[dpdk-dev] [PATCH 02/10] net/bnxt: fix probe failure in FreeBSD

[Kalesh A P]

From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>

In FreeBSD environment, nic_uio driver does not support interrupts
and rte_intr_callback_register() will fail to register interrupts
which in turn causes bnxt driver probe failure.

Fixed driver to ignore interrupt callback failures in FreeBSD.
Also fixed to not use a dedicated completion ring for async events
from FW and process these events on RXQ0 in FreeBSD.

Fixes: 6de4c538b393 ("net/bnxt: fix error handling in port start")
Fixes: 43f78b380f89 ("net/bnxt: retry IRQ callback deregistration")

[dpdk-dev] [PATCH 03/10] net/bnxt: fix to use correct IOVA mapping

[Kalesh A P]

From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>

Use rte_malloc_virt2iova() to obtain the IO address of a
virtual address obtained through rte_malloc().

Fixed to use the iova address returned by rte_memzone_reserve_aligned()
as the call always returns with populating "mz->iova" with
rte_malloc_virt2iova(mz->addr).

Removed redundant rte_mem_lock_page() call to lock the pages.

[dpdk-dev] [PATCH 04/10] net/bnxt: fix enable/disable VLAN filtering

[Kalesh A P]

From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>

There is no condition check for the user requested operation
for VLAN filtering. As a result, VLAN filtering is getting disabled
when the user enables/disables VLAN stripping on same port.

The function bnxt_hwrm_clear_l2_filter() didn't actually free
L2 filter in HW if the reference count of filter is zero.

Fixed it by incrementing the reference count of filter in
bnxt_alloc_filter() routine.

Because of the recent changes in bnxt_hwrm_clear_l2_filter(),
change was needed in the routine bnxt_set_default_mac_addr_op()
to destroy and re-create the default filter when the user
changes the default MAC of the port.

Fixes: 45eb28dd992b ("net/bnxt: fix to keep the L2 filter intact so it can be reused")
Fixes: 6118503d8071 ("net/bnxt: fix VLAN filtering")

[dpdk-dev] [PATCH 05/10] net/bnxt: fix enable/disable vlan strip

[Kalesh A P]

From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>

HWRM_VNIC_CFG command to configure vnic dynamically with
traffic running is not working. Driver has to free and
recreate the vnic and then reconfigure the vnic filters.

Fixes: 7fe5668d2ea3 ("net/bnxt: support VLAN filter and strip")

[dpdk-dev] [PATCH 06/10] net/bnxt: handle hw filter setting when port is stopped

[Kalesh A P]

From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>

Driver destroy the vnic when the port is brought down.
Port hw filter setting such as promiscuos, allmulti and
vlan filtering will be applied when port is started.

Fixed to return success silently for these callbacks
when port is stopped. Also fixed to clear "bp->dev_stopped"
before invoking bnxt_vlan_offload_set_op() in bnxt_dev_start_op().

[dpdk-dev] [PATCH 07/10] net/bnxt: fix a memory leak in port stop

[Kalesh A P]

From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>

The memory for mark table is allocated during port start.
But the allocated memory is freed only during port close
or driver unload which in turn causes a memory leakage
on each port start/stop.

Fixed it by moving the memory free to port stop.

[dpdk-dev] [PATCH 09/10] net/bnxt: release port upon close

[Kalesh A P]

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

Set RTE_ETH_DEV_CLOSE_REMOVE upon probe so all the private resources
for the port can be freed by rte_eth_dev_close().

[dpdk-dev] [PATCH 10/10] net/bnxt: fix to cap max rings to minimum of compl rings and stat contexts

[Kalesh A P]

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

Max Tx rings count could be lesser than max Rx rings in some
cases, so take this into account as well.

Account for stat contexts available(one for each ring) along with
no: of completion rings(one for each ring) to cap the max no: of
Tx /Rx rings that can be possibly created.

Fixes: f03e66cb ("net/bnxt: limit queue count for NS3/Stingray devices")
