Thanks, this seems to fix my problem.
I set
#define RL_RX_MAXDMA RL_RXDMA_UNLIMITED
#define RL_TX_MAXDMA RL_TXDMA_2048BYTES
and now at least my simple "ping torture tests" doesn't impress the
driver
any more.
Do such high values have any negative impact on the
performance/stability/
memory usage of the system? If not, couldn't these values be the
default?
Or the other way: Since recovery seems to be very easy, how difficult is
it for the driver to detect this condition and do an auto-recovery?
Yes, I know the RealTek are very ugly chips. Normally this card is
installed
into my Windows PC, but I had to swap the card with an I-EEPro in order
to
dualboot Solaris on this PC.
