[dpdk-dev] [PATCH 21/25] net/bnxt: provide switch info while VF-Reps are configured

[Ajit Khaparde]

From: Sriharsha Basavapatna <sriharsha.basavapa...@broadcom.com>

Some applications need switch_info of the device to be returned as a part
of eth_dev_info_get(). The offload logic in such applications could use
this info.

Fixes: 322bd6e70272 ("net/bnxt: add port representor infrastructure")
