uhci_check_intr() routine needs to be more careful about deciding when the end of a transfer has been detected. This allows me to remove the nasty workaround code from if_aue and if_cue. Receive performance is now much better for these adapters (500KB/sec vs. 350KB/sec). Also removed unused KUE_CUTOFF define from if_kuereg.h. Submitted by: Lennart Augustsson Reviewed by: n_hibma
