[dpdk-stable] [PATCH 2/4] net/bnxt: fix link speed setting with autoneg off

[dpdk-stable] [PATCH 2/4] net/bnxt: fix link speed setting with autoneg off

[Ajit Khaparde]

When Autoneg is turned off especially on remote side,
link does not come up. This patch fixes that.

[dpdk-stable] [PATCH 3/4] net/bnxt: add 100G speed config capability
