Tx Error 82 is a tx reclaim error.  It almost always is
caused by another host on the network doing a late transmit
when this host is already transmitting.  The reason the
other host does this: it's in full duplex mode on a half-duplex
network.

The patch which you have proposed doesn't fix the problem - it
simply allows the NIC's retransmit logic to function in this
case.  It'll resend the packet and it will *seem* that all
is well.  But you still have that host out there somewhere
running full-duplex.

Please send us the driver startup log messages, the output
of mii-diag and the output of vortex-diag, as described
in the final section of

And also please check your EEPROM settings using 
3com's DOS-based diagnostic tool,

Thanks.
