[dpdk-dev] [PATCH v2 7/9] net/bnxt: fix autoneg on 10GBase-T links

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

We are not passing proper speed mask causing autoneg to not work
properly on 10GBase-T links. Use supported speeds from phy_qcfg
for auto mask to fix this.

Fixes: 7bc8e9a227cc ("net/bnxt: support async link notification")
