I've done a little testing under various loads. The driver switches
chip to store and forward mode soon during initial use after attaching
(I also get few messages about watchdog timeouts together with 
"increasing TX threshold"). But it seems to work OK.
I haven't done any serious performance testing (maximum speed it
could reach was ~ 5Mb/s on 100baseTX/FD) nor attach/detach tests.

yes, it wasn't recognized before

I don't see a way how it could break other cards' functionality - should
be no concerns here

I don't see a real reson not to use more complete description. There are
few resons to use it:

0. More info is _always_ better. In any case, the message will take 2 lines
on console, so shortening the description will not gain anything
1. the description in `pciconf -lv` does not show card's version and chipset
2. when PCI IDs for previous card versions will be added, the description will
need to be changed anyway to include the version number
