[dpdk-dev] [PATCH 2/3] net/bnxt: fix number of mac addresses for VMDQ support

[Ajit Khaparde <ajit.khaparde@broadcom.com>]

We were hardcoding the max MAC addresses to 32, while the HW
can support more than that. This was restricting the number of VMDQ
pools that we could support. Use the value obtained from FW instead.
