Subject: [PATCH] net/bnxt: avoid invalid vnic id in set L2 Rx mask
[ upstream commit 1b533790f44ee160bae86bdcc5307d7b52225726 ]
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.
Fixes: 244bc98b0da7 ("net/bnxt: set L2 Rx mask")
