Larry Finger 54328e6404 rtlwifi: rtl8821ae: Fix system lockups on boot 
In commit 1277fa2ab2 ("rtlwifi: Remove the clear interrupt routine from all
drivers"), the code that cleared all interrupt enable bits before setting them
was removed for all PCI drivers. This fixed an issue that caused TX to be
blocked for 3-5 seconds. On some RTL8821AE units, this change causes soft
lockups to occur on boot. For that reason, the portion of the earlier commit
that applied to rtl8821ae is reverted. Kernels 4.1 and newer are affected.

See http://marc.info/?l=linux-wireless&m=144373370103285&w=2 and
https://bugzilla.opensuse.org/show_bug.cgi?id=944978 for two cases where
this regression affected user systems. Note that this bug does not appear on
any of the developer's setups. For those users whose systems are affected
by the TX blockage, but do not lock up on boot, a module parameter is added
to disable the interrupt clear
