I have been using an rtl8139 with the 1.17 driver and have found that it

locks up when under stress. Looking at the mailing list, this seems to
be a known problem and the workaround is to down and up the interface
In my case I have found that the card locks up when the status in the
interrupt handler function is 0x20 or 0x21.
Has anyone else seen this problem with the 1.17 driver?
I have attached a diff which seems to solve the problem when using the
1.17 driver. I would appreciate feedback as to whether my approach is
appropriate here (I re-enable the Rx and Tx and I am sure that you are
all far more familiar with this hardware than I am - so can probably
think of something better!!)
