[dpdk-dev] [PATCH 3/7] net/bnxt: fix rss hash configuration

[Ajit Khaparde]

While configuring RSS, the FW needs to know the rss_hash_mode that needs
to be initialized.
Set hash mode to HWRM_VNIC_RSS_CFG_INPUT_HASH_MODE_FLAGS_DEFAULT
to allow the FW to use the global mode already configured in the device.

Fixes: bcd4bcc4426f ("net/bnxt: configure RSS")

[dpdk-dev] [PATCH 4/7] net/bnxt: fix to use 1st completion ring for forwarding and async events

[Ajit Khaparde]

In order to save completion resource, use the first completion ring from
PF or VF as the default completion ring for async event & HWRM forward
response handling. Add bnxt_hwrm_set_async_event_cr() to set
async_event_cr for either PF or VF.

Fixes: 7bc8e9a227cc ("net/bnxt: support async link notification")

[dpdk-dev] [PATCH 5/7] net/bnxt: fix VF resource allocation

[Ajit Khaparde]

If the resource requirement of a VF is more than what is allotted
to it by the FW, a VF can request to reallocate some of the resources.

This is possible only when the NIC is running the Resource Manager aware
CHiMP FW.

If necessary, calculate Tx and Rx ring count using the new RM API.
Otherwise use the Tx and Rx ring count as-is. Update the cp ring count
based on the Tx and Rx ring count.

Fixes: b7778e8a1c00 ("net/bnxt: refactor to properly allocate resources for PF/VF")

Indicate PKT_RX_IP_CKSUM_UNKNOWN or PKT_RX_L4_CKSUM_UNKNOWN
for such frames.

Hi Ajit,

[dpdk-dev] [PATCH v2 3/7] net/bnxt: fix RSS hash configuration

[Ajit Khaparde]

While configuring RSS, the FW needs to know the rss_hash_mode that needs
to be initialized.
Set hash mode to HWRM_VNIC_RSS_CFG_INPUT_HASH_MODE_FLAGS_DEFAULT
to allow the FW to use the global mode already configured in the device.

[dpdk-dev] [PATCH v2 4/7] net/bnxt: fix to use 1st cmpl ring for fwd and async event

[Ajit Khaparde]

In order to save completion resource, use the first completion ring from
PF or VF as the default completion ring for async event & HWRM forward
response handling. Add bnxt_hwrm_set_async_event_cr() to set
async_event_cr for either PF or VF.

[dpdk-dev] [PATCH v2 5/7] net/bnxt: fix VF resource allocation

[Ajit Khaparde]

If the resource requirement of a VF is more than what is allotted
to it by the FW, a VF can request to reallocate some of the resources.

This is possible only when the NIC is running the Resource Manager aware
CHiMP FW.

If necessary, calculate Tx and Rx ring count using the new RM API.
Otherwise use the Tx and Rx ring count as-is. Update the cp ring count
based on the Tx and Rx ring count.

Fixes: b7778e8a1c00 ("net/bnxt: refactor to properly allocate resources for PF/VF")

[dpdk-dev] [PATCH v2 7/7] net/bnxt: fix Rx checksum flags

[Ajit Khaparde]

For frames where the hardware is not able to calculate checksum
we are indicating such frames to be bad. And that is incorrect.
Indicate PKT_RX_IP_CKSUM_UNKNOWN or PKT_RX_L4_CKSUM_UNKNOWN
for such frames.

Fixes: 7ec39d8c524b ("net/bnxt: update status of Rx IP/L4 CKSUM")
