The ASIX USB NICs are capable of autodetecting the Ethernet link speed and reporting it via PLSR but will not automatically update the relevant GM and PS bits in MSR. The result is that a non-gigabit link will fail to send or receive any packets. The interrupt endpoint used to report link state includes the values of the PHY BMSR and LPA registers. These are not sufficient to differentiate between 100Mbps and 1000Mbps, since the LPA_NPAGE bit does not necessarily indicate that the link partner is advertising 1000Mbps. Extend axge_check_link() to write the MSR value based on the link speed read from PLSR, and simplify the interrupt endpoint handler to merely trigger a call to axge_check_link().
