Subject: net/bnxt: fix unnecessary HWRM command
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=f456684ac2afafc97106ab8d997c9aa477f6b15f;p=dpdk.git

net/bnxt: fix unnecessary HWRM command

During probe, driver issues HWRM_CFA_ADV_FLOW_MGNT_QCAPS command.
But it is not using the command response anywhere which makes the
fw call redundant.

Remove the unnecessary HWRM_CFA_ADV_FLOW_MGNT_QCAPS call to fw.
Remove the redundant flow_flags in bnxt struct.

Fixes: afef822b2e1b ("net/bnxt: support creating SMAC and inner DMAC filters")
