[dpdk-dev] [PATCH 2/2] net/bnxt: fix link handling and configuration
Ajit Khaparde
ajit.khaparde at broadcom.com
Thu Nov 9 18:46:28 CET 2017
Remove a case where we were sending a depricated field to the FW.
There is no need to send auto_link_speed to the FW.
Also set the auto_mode correctly depending on the setting requested.
Fixes: 7bc8e9a227cc ("net/bnxt: support async link notification")
