Subject: [PATCH v3 3/4] wifi: rtw88: set pkg_type correctly for specific rtw8821c variants
Date:   Mon, 17 Apr 2023 16:03:57 +0200

According to the vendor driver the pkg_type has to be set to '1'
for some rtw8821c variants. As the pkg_type has been hardcoded to
'0', add a field for it in struct rtw_hal and set this correctly
in the rtw8821c part.
With this parsing of a rtw_table is influenced and check_positive()
in phy.c returns true for some cases here. The same is done in the
vendor driver. However, this has no visible effect on the driver
here.
