Gleb Mazovetskiy 86136bf623 tcp: configurable source port perturb table size
[ Upstream commit aeac4ec8f46d610a10adbaeff5e2edf6a88ffc62 ]

On embedded systems with little memory and no relevant
security concerns, it is beneficial to reduce the size
of the table.

Reducing the size from 2^16 to 2^8 saves 255 KiB
of kernel RAM.

Makes the table size configurable as an expert option.

The size was previously increased from 2^8 to 2^16
in commit 4c2c8f03a5ab ("tcp: increase source port perturb table to
2^16").
