Subject: net/bnxt: fix setting VLAN anti spoof with same value
X-Git-Tag: spdx-start~2306

net/bnxt: fix setting VLAN anti spoof with same value

If the current VLAN anti spoof setting is same as the new value,
the firmware can return an error. Call the HWRM command to update
the new setting if it is different from the current value.
