iwlwifi: add {ack, plpc}_check module parameters
commit b7977ffaab5187ad75edaf04ac854615cea93828 upstream.
Add module ack_check, and plcp_check parameters. Ack_check is disabled
by default since is proved that check ack health can cause troubles.
Plcp_check is enabled by default.
This prevent connection hangs with "low ack count detected" messages.
