From: David Sommerseth
In commit ce637abdafdc19547fc97192033a4d1703ecaf23 the Linux 2.2 support
was removed. When this happened an extra error check was avoided which
would normally kicked in if the tun/tap device would not be available.
Instead the following line was filling the log continously:
Thu Nov 24 22:33:15 2011 read from TUN/TAP : File descriptor in bad state
(code=77)
This patch changes the msg() declarations to use the M_FATAL *) flag,
which will halt the execution of the program in these error sitauations.
As the program will really halt, the return declarations was also removed.
*) #define M_ERR (M_FATAL | M_ERRNO) (from error.h)
