Subject: [PATCH] linux-user: Use EPROTONOSUPPORT for unimplemented netlink protocols
Date: Mon,  6 Jul 2020 17:10:36 -0700	[thread overview]
Message-ID: <20200707001036.1671982-1-jkz@google.com> (raw)

Linux uses the EPROTONOSUPPORT error code[1] if the users requests a
netlink socket with an unsupported netlink protocol. This change
switches linux-user to use the same code as Linux, instead of
EPFNOSUPPORT (which AFAIK is just an anachronistic version of
EAFNOSUPPORT).

Tested by compiling all linux-user targets on x86.
