[dpdk-dev] [PATCH v2 2/3] net/bnxt: fix set_rx_mask from using invalid vnic id

[Ajit Khaparde]

In some cases bnxt_hwrm_cfa_l2_set_rx_mask is being called before
VNICs are allocated. The FW returns an error in such cases.
Move bnxt_init_nic to bnxt_dev_init such that the ids are initialized
to an invalid id.
Prevent sending the command to the FW only with a valid vnic id.

Hi Ajit,

Still getting warnings with check-git-log.sh [1], can you please check?

$ ./devtools/check-git-log.sh -3

It's better to use real english words or well know abbreviations for patch titles.
Example:
	net/bnxt: avoid invalid vNIC in L2 Rx mask
	net/bnxt: fix mbuf data offset initialization
