FYI,
I have modified my freeware afe/mxfe ethernet drivers so that the export
kstat_intr's for "afec" and "mxfec" (ala hme et. al.) The fixes are in
version 1.0.7 of etherdrivers at http://sol-enet.sourceforge.net/
As far as I know, they are the only GLD based NIC drivers to do this.
FYI, I'm told that Alan DuBoff is working on getting afe into Solaris.
(This NIC driver primarily supports the ADMtek chipset used in a large
number of NIC products, both PCI and Cardbus. The most common example
are the 10/100 ethernet cards produced by Linksys, though there are a
bunch of smaller vendors which also use them. It is possibly the most
common chipset used in 10/100 cardbus devices.)
