From c032705ebfed32a6dcda72d83c54f060d4bf1e6e Mon Sep 17 00:00:00 2001 From: Lennert Buytenhek Date: Mon, 25 May 2015 15:38:24 +0300 Subject: [PATCH] ieee802154 socket: Return EMSGSIZE from raw_sendmsg() if packet too big. The proper return code for trying to send a packet that exceeds the outgoing interface's MTU is EMSGSIZE, not EINVAL, so patch ieee802154's raw_sendmsg() to do the right thing. (Its dgram_sendmsg() was already returning EMSGSIZE for this case.)
