Does RHEL support BIG TCP for high-speed networking?

Issue

• Does RHEL support BIG TCP for high-speed networking?
• We would like support for Big TCP to overcome current limits and reduce TCP/IP stack overhead with 200Gbit and 400Gbit being hit within data centers. Big TCP is about going past the current 64KB TSO/GRO packet limit size for IPv6 traffic by way of the IPv6 Jumbogram extension header. Enabling big TCP across both send/receive systems can lead to huge throughput improvements and lower latencies for high speed networking environments.
