This makes btusb to queue ACL and events during a polling interval
by using of a delayed work, with the interval working as a time window
where frames received from different endpoints are considered to be
arrived at same time and then attempt to resolve potential conflics by
processing the events ahead of ACL packets.
It worth noting though that priorizing events over ACL data may result
in inverting the order compared to how they appeared over the air, for
instance there may be packets received before a disconnect event that
will be discarded and unencrypted packets received before encryption
change which would considered encrypted, because of these potential
changes on the order the support for queuing during the polling
interval is not enabled by default so it requires setting
force_poll_sync debugfs while the adapter is down.

Like skb_pull but returns the original data pointer before pulling the
data after performing a check against sbk->len.
This allows to change code that does "struct foo *p = (void *)skb->data;"
which is hard to audit and error prone, to:
p = skb_pull_data(skb, sizeof(*p));
if (!p)
return;
Which is both safer and cleaner.

This patch changes mac80211 rate control for the ath9k driver. The rate lookup
per packet is changed from legacy usage of ieee80211_get_tx_rates() to the new
rate table based lookup in struct ieee80211_sta->rates.
The most recent rate control API, introduced with commit 0d528d85c5
("mac80211: improve the rate control API"), allows drivers to directly get
rates from ieee80211_sta->rates. This is not used by every driver yet, the
translation/merge is currently performed in ieee80211_get_tx_rates. This patch
changes the behaviour and avoids the call to ieee80211_get_tx_rates and
subsequent calls. ath9k now directly reads rates from sta->rates into its rate
table. Cause ath9k does not expect rate selection in SKB->CB, the table merge
does not consider rate array in SKB->CB except for the first entry (used for
probing).
Tested with a 8devices Rambutan with QCA9558 SoC by performing two runs, one
without the patch and one with. Generated traffic between AP and multiple STAs
in each run, measured throughput and captured rc_stats. Comparison of both
runs resulted in same rate selection and no performance loss or other negative
effects.

On an imx6dl-pico-pi board with a QCA9377 SDIO chip, simply trying to
connect via ssh to another machine causes:
[ 55.824159] ath10k_sdio mmc1:0001:1: failed to transmit packet, dropping: -12
[ 55.832169] ath10k_sdio mmc1:0001:1: failed to submit frame: -12

[ 55.919887] ath10k_sdio mmc1:0001:1: failed to push frame: -12
, leading to an ssh connection failure.
One user inspected the size of frames on Wireshark and reported
the followig:
"I was able to narrow the issue down to the mtu. If I set the mtu for
the wlan0 device to 1486 instead of 1500, the issue does not happen.
The size of frames that I see on Wireshark is exactly 1500 after
setting it to 1486."
Clearing the HI_ACS_FLAGS_ALT_DATA_CREDIT_SIZE avoids the problem and
the ssh command works successfully after that.
Introduce a 'credit_size_workaround' field to ath10k_hw_params for
the QCA9377 SDIO, so that the HI_ACS_FLAGS_ALT_DATA_CREDIT_SIZE
is not set in this case.
Tested with QCA9377 SDIO with firmware WLAN.TF.1.1.1-00061-QCATFSWPZ-1.
