[Michael Straube]

The local variables rx_packet_offset and max_recvbuf_sz in
rtw_restructure_ht_ie() are set but never used. Remove them.

[PATCH 2/6] staging: r8188eu: remove unused cases from GetHalDefVar8188EUsb()

[Michael Straube]

GetHalDefVar8188EUsb() is never called with HAL_DEF_DRVINFO_SZ,
HAL_DEF_RA_DECISION_RATE, HAL_DEF_RA_SGI and HAL_DEF_PT_PWR_STATUS.
Remove these cases from the function.

[PATCH 3/6] staging: r8188eu: max_rx_ampdu_factor is always MAX_AMPDU_FACTOR_64K

[Michael Straube]

The local variable max_rx_ampdu_factor in rtw_restructure_ht_ie() and
issue_action_BA() is always set to MAX_AMPDU_FACTOR_64K. Remove the
variable from both functions and use MAX_AMPDU_FACTOR_64K directly.

The case HW_VAR_MAX_RX_AMPDU_FACTOR in GetHalDefVar8188EUsb() is now
unused and can be removed.
