Update mxge(4) firmware to 1.4.48b (latest available) from Myricom.
Pertinant highlights from Myricom CHANGES file include: - Make sure invalid external smbus activity cannot affect performance - Fix to avoid a bug where the link could sometimes stay reported as up on after unplugging the cable. - For 8B NIC, make smbus connection passive at init to avoid possible address conflicts - Increase number of slices to 17 for multi-slice fw - Fix a bug where packets dropped because of link_overflow could be occasionally reported as bad_crc32 - Add selectable failover strategy for dual-port chip: symmetric or primary/backup - On failover, send RARP broadcast to make the change immediately known to the network - Change endianess for PCI Device Serial Number - For dual-port NICs, time to failover is now a few microsecs instead of a few millisecs. MFC after: 3 days
