Subject: tcp: cleanup ca_state mess in tcp_timer
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=bc079e9ede5fb0225bd3e84891a6266f77142094;p=openwrt%2Fstaging%2Fblogic.git

tcp: cleanup ca_state mess in tcp_timer

Redundant checks made indentation impossible to follow.
However, it might be useful to make this ca_state+is_sack
indexed array.
