Most likely the driver for the card you are using.

fix the driver. Look where it emits the particular message and do something
more intelligent than a stupid message.. reset the card if nothing else helps.
Alternatively have some log-watcher do the id-down/if-up for you if it sees
the message. To be sure setup a cronjob that tries a few ping's and does the
same if none returns

if it is mostly TCP connection try to halve the window size. Should be
decribed somewhere in the kernel docs.
