Subject[PATCH net-next v2 1/6] bonding: rename 802.3ad's struct port to ad_port
Date
The intention is to reuse "port" in place of "slave" in the bonding driver
after making this change, as port is consistent with the bridge and team
drivers, and allows us to remove socially problematic language from the
bonding driver.
