Subject: net/bnxt: provide switch info if VFR are configured
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=9b842a93e21afb16226577c8bb2a7a5bca60c2e0;p=dpdk.git

net/bnxt: provide switch info if VFR are configured

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. Pass this info to the when VF
representors are configured.

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