Generalize the ULP infrastructure that was recently introduced to
support kTLS. This adds a SO_ULP socket option and creates new fields in
sock structure for ULP ops and ULP data. Also, the interface allows
additional per ULP parameters to be set so that a ULP can be pushed
and operations started in one shot.
This patch sets:
- Minor dependency fix in inet_common.h
- Implement ULP infrastructure as a socket mechanism
- Fixes TCP and TLS to use the new method (maintaining backwards
API compatibility)
- Adds a ulp.txt document
Tested: Ran simple ULP. Dave Watson verified kTLS works.
-v2: Fix compliation errors when CONFIG_ULP_SOCK not set.
-v3: FIx one more build issue, check that sk_protocol is IPPROTO_TCP
in tsl_init

sock: ULP infrastructure
tcp: Adjust TCP ULP to defer to sockets ULP
