[PATCH 08/11] staging: r8188eu: clarify the contents of the delba params

From: Martin Kaiser
Date: Thu Jun 02 2022 - 15:38:41 EST


The delba parameters field contains an initiator/receiver flag and the
tid. The caller of issue_action_BA passes these components in the status
parameter.

Extract the two components from status and use u16_encode_bits to copy
them into the parameters field. This should clarify what's going on and
should make it easier to replace the status parameter in the future.
