Version 1.13 and later of kern_compat.h has the following to work around
this problem:

#if !defined(NETIF_MSG_MAX) || NETIF_MSG_MAX < 0x8000
#define NETIF_MSG_MISC 0x8000
#endif
#if !defined(NETIF_MSG_MAX) || NETIF_MSG_MAX < 0x10000
#define NETIF_MSG_RXFILTER 0x10000
#endif

These are bogus warnings from the compiler.
We are filling with duplicate values and don't care which order the
assignment is done.  Still, the v0.95g version of tulip.c changes the
code to avoid the warning.

Both updates are now at
