19:42:45 working on the RTM_IFINFO message I ran into a problem:
now the kernel will panic in rt_msg1() when trying to send a
RTM_IFINFO message, because the size of the message is greater
than MHLEN when stats are 64bit counters. On alpha, MSIZE is
256, on all others 128 (which means sparc64 is probably brocken
at this time :). I can see 3 ways of solving this: 1) remove the
stats from the RTM_IFINFO message. I wonder if any program
use this part of the message but this breaks compatibility. 2)
bump MSIZE to 256 on all port. I don't know what impact this
will have    on memory usage. 3) Define a new type (ifstat_t)
which can be either 32 or 64 bit, defined    per port in a
machine-dependant header (which one ? machine/types.h ?).    So
we could keep 32 bit counters and MSIZE to 128 on machines with
slow CPU    or low memory and 64bit otherwise.  1) is probably
evil. I would go for
