cxgb3 firmware missing

[willmo]

The main firmware binary for the Chelsio T3 NIC (cxgb3 driver) is missing from all recent Ubuntu releases. It keeps getting removed:

These commits should have KEPT cxgb3/t3fw-7.12.0.bin, which is the current version, but removed cxgb3/t3fw-7.0.0.bin, cxgb3/t3fw-7.1.0.bin, and cxgb3/t3fw-7.4.0.bin, which are indeed obsolete.

See here that 7.12 is the current version:

Here's what one sees in dmesg:
