In Genoa SDIO ADMA implementation Host sends packets to FW in
multiples of SDIO Block size.
If the packet/bundle is not block aligned Host adds padding at the
end of Packet/Bundle.
If the TX packet plus padding exceeds one FW TX Buffer, Padding data
will occupy the next FW TX buffer. Same applies for bundle TX packet.
For above scenario, HTC_FLAGS_PADDING_CHECK of HTC header Flags is used
to notify the FW that - Padding data follows the currentHTC packet
Since the padding data will take one extra FW Tx Buffer, host need to
handle the extra Tx credit being used by the padding data/buffer

Per the Linux Kernel coding style, as enforced by the kernel
checkpatch script, pointers should not be explicitly compared to
NULL. Therefore within dp replace any such comparisons with logical
operations performed on the pointer itself.

1) Genoa FW by default enables HI_ACS_FLAGS_SDIO_REDUCE_TX_COMPL_SET.
When this flag is enabled, credits are reported through
HTT_T2H_MSG_TYPE_TX_CREDIT_UPDATE_IND and not through
HTT_T2H_MSG_TYPE_TX_COMPL_IND.
However when TSF and PTP features are enabled we need to get TX
Completions from FW.
Since credits can also be updated through TX Completions
we need to disable updation of credits through TX Completion for Genoa.
2) Enable flag : cfg_ctx->tx_free_at_download to free ol tx descriptors at
download.

Several packets are sent to firmware in htt_htc_attach_all(), back to
back. However, if one of the latter packets fails to send for some
reason, the previous packets are not flushed. This leads to a number of
leaks under error conditions.
If a packet fails to send in htt_htc_attach_all(), flush the endpoint
before returning failure to the upper layers.

by a lock when packets are being removed from it, which may
