tcp/session: tx optimizations
- cache and reuse tcp options and rcv_wnd for session layer tx bursts - avoid reading/setting total_length_not_including_first_buffer. It's part of a buffer's second cache line so it comes at a "cost". Change-Id: Id18219c2f7e07cf4c63ee74f9cdd9e5918904036 Signed-off-by: Florin Coras <fcoras@cisco.com>
