The code for 10.4 is here: https://github.com/freebsd/freebsd-src/blob/releng/10.4/sys/dev/hyperv/netv= sc/if_hn.c#L1008 Since the only media supported is autoselect, it seems reasonable to just return 0 from hn_ifmedia_upd() instead of EOPNOTSUPP. Patched on 15-current, this results in no error for "autoselect" and will error for unregistered m= edia types. # ifconfig hn0 media autoselect # ifconfig hn0 media 100baseT ifconfig: SIOCSIFMEDIA (media): Device not configured An early review D4611 did have hn_ifmedia_upd() return 0 but was abandoned.= A subsequent review D4852 has this function returning EOPNOTSUPP. Allowing selection of the current (and only) registered media type seems reasonable rather than throwing an error. I'm going to try contacting a cou= ple of the contributors to the reviews to see if they agree. --=20 You are receiving this mail because: You are the assignee for the bug.=
