[c-nsp] pa-feisl-tx cards

[Joe Pruett]

i want to add some fast ethernet ports to a 7206vxr and i see lots of 
feisl cards out there, but i can't find enough info on the web to tell if 
they function as normal fastethernet interfaces and support 802.1q 
tagging. i understand they are eol'ed, but seem to be supported still.  i 
can live without autonegotiation (since cisco has never gotten that right 
:-).

can anyone shed light on just how different the isl versions are from the 
regular fe cards?
