FW team asks to be able to not support RED even if NIC is capable
of buffering for testing and experimentation. Add an opt-out flag.

This change allows to search for the right cookie and accepts old ones
(announcing a new one if it has changed).
__tcp_fastopen_cookie_gen_with_ctx() allows to generate a cookie based
on a given TFO-context. A later patch will cleanup the duplicate code.

Currently, TFO only allows a single TFO-secret. This means that whenever
the secret gets changed for key-rotation purposes, all the previously
issued TFO-cookies become invalid. This means that clients will fallback
to "regular" TCP, incurring a cost of one additional round-trip.

Print the list of the TFO-keys with a comma separated. For setting the

Instead of having a single TFO-context, we now have a list of
tcp_fastopen_context, bounded by TCP_FASTOPEN_CTXT_LEN (set to 2).
This enables us to do a rolling TFO-key update that allows the server to
accept old cookies and at the same time announce new ones to the client
(see follow-up patch).
We can actually easily reuse __tcp_fastopen_cookie_gen_with_ctx to
generate the cookie based on a give TFO-context.
This cleans up some of the code.

When HW lag is set/unset, roce must not be enabled on the port, as such
we wrap such changes with roce enable/disable either directly or through
re-creation of IB device.
Currently, lag and sriov are mutually exclusive, so by definition this
code doesn't run under sriov.
