3c60e22da7
includes support for the NIC and TOE features of the 40G, 10G, and 1G/100M cards based on the T5. The ASIC is mostly backward compatible with the Terminator 4 so cxgbe(4) has been updated instead of writing a brand new driver. T5 cards will show up as cxl (short for cxlgb) ports attached to the t5nex bus driver. Sponsored by: Chelsio
