tcp: Fit struct tcp_conn into a single 64-byte cacheline
...by: - storing the chained-hash next connection pointer as numeric reference rather than as pointer - storing the MSS as 14-bit value, and rounding it - using only the effective amount of bits needed to store the hash bucket number - explicitly limiting window scaling factors to 4-bit values (maximum factor is 14, from RFC 7323) - scaling SO_SNDBUF values, and using a 8-bit representation for the duplicate ACK sequence - keeping window values unscaled, as received and sent Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
