Change Details

Tested with ASIX MCS9922 hardware. Human-rate traffic is exchanged correctly at 9600 baud, and both devinfo -r / vmstat -i report that MSI interrupts are being used.

Tested with ASIX MCS9922 hardware: i.e. a Syba SD-PEX15022 dual PCIe UART card. vmstat -i reported that MSI interrupts were in use throughout. lrzsz ZMODEM receives and sends were reliable in both directions up to 56K, using a separate Linux machine with an ExpressCard PCIe UART. Testing at 115K showed CRC errors, presumably due to the low quality DB9 null-modem cable in use.
