[dpdk-dev] [PATCH 2/8] net/bnxt: fix switch domain allocation

[Kalesh A P <kalesh-anakkur.purayil@broadcom.com>]

From: Ajit Khaparde <ajit.khaparde@broadcom.com>

Allocate switch domain after the trusted VF capability is queried
from the FW. Currently we are calling the function earlier.
Since the switch domain is allocated only for PFs or trusted VF,
the current location of code fails to allocate the domain during init.
But during cleanup we try to free the domain incorrectly.
Fix the behavior by changing the sequence of function calls.

Fixes: 3127f99274b67 ("net/bnxt: refactor init/uninit")
