>Description:
        When large files are coppied over NFS the realtek driver stops
working.        This occurs after 1 minute or so, then I retry and then
it goes again for a minute or so.
        I get errors in dmesg like this:
        ----
        rl0: discard oversize frame (ether type 4471 flags 3 len 30037 >
max 1514)        rl0: discard oversize frame (ether type 1cd2 flags 3
len 30381 > max 1514)        ----
        The problem occurs on different hardware and on different
realtek cards.        Tested hardware:

Asus TX97XE with pentium 120 and 128mb ram, ide disk on the onboard
controller and        scsi disk on a adaptec 2940U2W
        And on ASUS P2B-DS with pentium 550 and 256mb ram, ide disk and
scsi disk connected        with a mylex acceleraid 150.
        I tested different type's of rl card's and with all these errors
occur.

        I found some problem reports of a xe0 card, with the same
problem report, but I        thought that the rl driver has no
connection with the xe driver.

I found also another mail on the lucky list, with exact the same problem

        Large file transfers via NFS
