If you had an etherteam 16i you really didn't want to be using it!
Of course, ICL used it as the standard ethernet card for
a few years!
Not that I kept any of them.

There was a hardware bug that meant that occaisionally
a receive packet would not be indicated to the host (not even
visible in the fifo) until the following packet arrived.

They would also reject received packets if the PHY signalled
a 'collision' even if the CRC was valid.
Most PHY only correctly detected collisions during transmit.
PHYs that correctly detect collision during RX were only
normally needed for MAC repeaters (which would also need
SQE disabled).
