There has been a coding error in rtl8821ae since it was first introduced,
namely that an 8-bit register was read using a 16-bit read in
_rtl8821ae_dbi_read(). This error was fixed with commit 40b368af4b75
("rtlwifi: Fix alignment issues"); however, this change led to
instability in the connection.
In commit 40b368af4b75 ("rtlwifi: Fix alignment issues"), the read
of REG_DBI_READ was changed from 16 to 8 bits. For unknown reasonsi
this change results in reduced stability for the wireless connection.
This regression was located using bisection.
