From: Arnaldo Carvalho de Melo Date: Mon, 25 Apr 2005 01:53:06 +0000 (-0700) Subject: [AX25] Introduce ax25_type_trans X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=56cb515628e6a831bb76783f282a71f7285dad33;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git [AX25] Introduce ax25_type_trans Replacing the open coded equivalents and making ax25 look more like a linux network protocol, i.e. more similar to inet.
