I noticed something similar this evening on a 3.1-STABLE box with an
SMC9432TX.  After cvsupping sources on 3/18/1999, I finished the upgrade
tonight; after building the new kernel, ping times to my default gateway
jumped from ~2ms to ~23ms.  Rebooting with my previous kernel (source from
~3/1/1999?) eliminates the problem.

Looking at http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/pci/if_tx.c it
looks like there has been some activity with if_tx.c recently... anyone
got any insight?

cheers:
andy
