Commit "net: phy: Add detection of 1000BaseX link mode support" added
support for not filtering out 1000BaseX mode from the PHY's supported
modes in genphy_config_init, but we have to make a similar change in
genphy_read_abilities in order to actually detect it as a supported mode
in the first place. Add this in.

We can avoid another indirect call per packet wrapping the rx
handler call with the proper helper.
To ensure that even the last listed direct call experience
measurable gain, despite the additional conditionals we must
traverse before reaching it, I tested reversing the order of the
listed options, with performance differences below noise level.
Together with the previous indirect call patch, this gives
~6% performance improvement in raw UDP tput.
v2 -> v3:
- use only the direct calls always available regardless of
the mlx5 build options
- drop the direct call list macro, to keep the code as simple
as possible for future rework
v1 -> v2:
- update the direct call list and use a macro to define it,
as per Saeed suggestion. An intermediated additional
macro is needed to allow arg list expansion

When calling debugfs functions, there is no need to ever check the
return value. The function can work or not, but the code logic should
never do something different based on this.
Also, there is no need to store the individual debugfs file name, just
remove the whole directory all at once, saving a local variable.

When the offchannel TX wait time expires, send the appropriate event.

cfg80211_remain_on_channel_expired is used to notify userspace when
the remain on channel duration expired by sending an event. There is
no such equivalent to CMD_FRAME, where if offchannel and a duration
is provided, the card will go offchannel for that duration. Currently
there is no way for userspace to tell when that duration expired
apart from setting an independent timeout. This timeout is quite
erroneous as the kernel may not immediately send out the frame
because of scheduling or work queue delays. In testing, it was found
this timeout had to be quite large to accomidate any potential delays.
A better solution is to have the kernel send an event when this
duration has expired. There is already NL80211_CMD_FRAME_WAIT_CANCEL
which can be used to cancel a NL80211_CMD_FRAME offchannel. Using this
command matches perfectly to how NL80211_CMD_CANCEL_REMAIN_ON_CHANNEL
works, where its both used to cancel and notify if the duration has
expired.

If HW advertises it has rate control, we skip all of the
rate control assignments, but sometimes the data we have
here is useful, especially so that we don't have to do
the lookups again on which rates are configured and are
supported.
So do the low rate assignment anyway to help out drivers
that might need it.

Even if we have a station, we currently call rate_control_send_low()
with the NULL station unless further rate control (driver, minstrel)
has been initialized.
Change this so we can use more information about the station to use
a better rate. For example, when we associate with an AP, we will
now use the lowest rate it advertised as supported (that we can)
rather than the lowest mandatory rate. This aligns our behaviour
with most other 802.11 implementations.
To make this possible, we need to also ensure that we have non-zero
rates at all times, so in case we really have *nothing* pre-fill
the supp_rates bitmap with the very lowest mandatory bitmap (11b
and 11a on 2.4 and 5 GHz respectively).
Additionally, hostapd appears to be giving us an empty supported
rates bitmap (it can and should do better, since the STA must have
supported for at least the basic rates in the BSS), so ignore any
such bitmaps that would actually zero out the supp_rates, and in
that case just keep the pre-filled mandatory rates.

A-MPDU. Drivers supporting A-MPDUs and Extended Key ID must actively
enforce that requirement due to the available two unicast keyIDs.

MPDUs when aggregating them and that they expect mac80211 to stop Tx
aggregation when rekeying a connection using Extended Key ID.

The packing facility is needed to decode Ethernet meta frames containing
source port and RX timestamping information.
The DSA driver selects CONFIG_PACKING, but the tagger did not, and since
taggers can be now compiled as modules independently from the drivers
themselves, this is an issue now, as CONFIG_PACKING is disabled by
default on all architectures.

qeth currently uses a fixed set of statically allocated cmd buffers for
the read and write IO channels. This (1) doesn't play well with the single
RCD cmd we need to issue on the data channel, (2) doesn't provide the
necessary flexibility for certain IDX improvements, and (3) is also rather
wasteful since the buffers are idle most of the time.
Add a new type of cmd buffer that is dynamically allocated, and keeps
its ccw chain in the DMA data area. Since this touches most callers of
qeth_setup_ccw(), also add a new CCW flags parameter for future usage.

OSN currently provides a custom code path to submit IPA cmds, without
waiting for the cmd response. Replace it with qeth_send_ipa_cmd(), which
uses the common qeth_send_control_data() IO infrastructure.
By setting a custom iob->callback, we can now provide feedback to the
caller about whether the cmd has been successfully submitted to HW.
Since the callback then immediately wakes up the reply-waiter object, we
maintain the old behaviour of returning early without waiting for the
response.
