[PATCH v2 07/25] tcp: Use BIT() for OPTION_* constants

From: Leonard Crestez
Date: Mon Nov 01 2021 - 12:35:54 EST


Extending these flags using the existing (1 << x) pattern triggers
complaints from checkpatch.

Instead of ignoring checkpatch modify the existing values to use BIT(x)
style in a separate commit.
