From 2850beb940a4a05e901fe608cf7d45dc8efbb49e Mon Sep 17 00:00:00 2001 From: Ian Lance Taylor Date: Sat, 25 Jul 2015 00:01:04 +0000 Subject: [PATCH] syscall: Add ioctl consts from if_tun.h During the gccgo build define constants from some header files are processed by mksysinfo.sh and added to syscall.go. In some cases the constants are based on macros which are not processed correctly by mksysinfo.sh. This adds the support to generate the correct values for the TUN* constants from linux/if_tun.h.
