Subject: cxgb4: increase max tx rate limit to 100 Gbps
Patch-mainline: v4.17-rc1
Git-commit: d185efc1da089b968dfe1825329c51820d661755
References: bsc#1097585 bsc#1097586 bsc#1097587 bsc#1097588 bsc#1097583 bsc#1097584
T6 cards can support up to 100 G speeds. So, increase
max programmable tx rate limit to 100 Gbps.
