Select the host interface configuration according to the capabilities of
the host if the host provided them. This is currently provided only when
connecting PHY that is inside a SFP.

The PHY supports several configurations of host communication:
- always communicate with host in 10gbase-r, even if copper speed is
  lower (rate matching mode),
- the same as above but use xaui/rxaui instead of 10gbase-r,
- switch host SerDes mode between 10gbase-r, 5gbase-r, 2500base-x and
  sgmii according to copper speed,
- the same as above but use xaui/rxaui instead of 10gbase-r.

This mode of host communication, called MACTYPE, is by default selected
by strapping pins, but it can be changed in software.

This adds support for selecting this mode according to which modes are
supported by the host.

This allows the kernel to:
- support SFP modules with 88X33X0 or 88E21X0 inside them

Note: we use mv3310_select_mactype() for both 88X3310 and 88X3340,
although 88X3340 does not support XAUI. This is not a problem because
88X3340 does not declare XAUI in it's supported_interfaces, and so this
function will never choose that MACTYPE.

Pass the supported PHY interface types to phylib if the PHY we are
connecting is inside a SFP, so that the PHY driver can select an
appropriate host configuration mode for their interface according to
the host capabilities.

For example the Marvell 88X3310 PHY inside RollBall SFP modules
defaults to 10gbase-r mode on host's side, and the marvell10g
driver currently does not change this setting. But a host may not
support 10gbase-r. For example Turris Omnia only supports sgmii,
1000base-x and 2500base-x modes. The PHY can be configured to use
those modes, but in order for the PHY driver to do that, it needs
to know which modes are supported.

mlx5 xsk updates part3 2022-09-30

The gist of this 4 part series is in this patchset's last patch

This series contains performance optimizations. XSK starts using the
batching allocator, and XSK data path gets separated from the regular
RX, allowing to drop some branches not relevant for non-XSK use cases.
Some minor optimizations for indirect calls and need_wakeup are also
included.

Other than that, this series adds a few features to the mlx5e
implementation of XSK:

1. XDP metadata support on XSK RQs.

2. RSS contexts support for XSK RQs.

3. Some other optimizations

4. Last but not least, change the queuing scheme, so that XSK RQs no longer
use higher indices, but replace the regular RQs.

Maxim Says:
==========

In the initial implementation of XSK in mlx5e, XSK RQs coexisted with
regular RQs in the same channel. The main idea was to allow RSS work the
same for regular traffic, without need to reconfigure RSS to exclude XSK
queues.

However, this scheme didn't prove to be beneficial, mainly because of
incompatibility with other vendors. Some tools don't properly support
using higher indices for XSK queues, some tools get confused with the
double amount of RQs exposed in sysfs. Some use cases are purely XSK,
and allocating the same amount of unused regular RQs is a waste of
resources.

This commit changes the queuing scheme to the standard one, where XSK
RQs replace regular RQs on the channels where XSK sockets are open. Two
RQs still exist in the channel to allow failsafe disable of XSK, but
only one is exposed at a time. The next commit will achieve the desired
memory save by flushing the buffers when the regular RQ is unused.

As the result of this transition:

1. It's possible to use RSS contexts over XSK RQs.

2. It's possible to dedicate all queues to XSK.

3. When XSK RQs coexist with regular RQs, the admin should make sure no
unwanted traffic goes into XSK RQs by either excluding them from RSS or
settings up the XDP program to return XDP_PASS for non-XSK traffic.

4. When using a mixed fleet of mlx5e devices and other netdevs, the same
configuration can be applied. If the application supports the fallback
to copy mode on unsupported drivers, it will work too.

==========

mlx5e_free_rx_wqe loops over all fragments, calling mlx5e_page_release

whether it's an XSK RQ or a regular one for each fragment. Using the
fact that XSK doesn't support multiple fragments, it can be optimized

1. Make an early check for XSK and call its deallocator directly, saving
3 branches (loop condition, frag->last_in_page and selection of

2. Call the regular deallocator directly in the non-XSK case, saving a

XSK provides a function to allocate frames in batches for more efficient
processing. This commit starts using this function on legacy RQ, adding
a special case for XSK. The new branch introduced basically replaces the
branch that was removed from the same place a few commits before.

A check is made that DMA sync is not needed, because the batching
allocator falls back to returning one frame when DMA sync is needed, and
this is best handled by the loop in the standard case.

Legacy RQ allocates WQEs in batches. If the batch allocation fails, the
pages of the allocated part are released. This commit changes this
behavior to allow to use the pages that have been already allocated.

After this change, we need to be careful about indexing rq->wqe.frags[].
The WQ size is a power of two that divides by wqe_bulk (8), and the old
code used whole bulks, which allowed to use indices [8*K; 8*K+7] without
overflowing. Now that the bulks may be partial, the range can start at
any location (not only at 8*K), so we need to wrap them around to avoid

When fragments of different WQEs share the same page, mlx5e_post_rx_wqes
must wait until the old WQE stops using the page, only then the new WQE
can allocate the new page. Essentially, it means that if WQE index i is
still in use, the allocation must stop before `i % bulk`, where bulk is
the number of WQEs that may share the same page.

As bulk is always a power of two, `i % bulk = i & (bulk - 1)`, and the
new wqe_index_mask field will be equal to `bulk - 1`.

At the same time, wqe_bulk remains for optimization purposes and stores
`max(bulk, 8)`, which allows to skip the allocation until we have at
least 8 WQEs free.

The MLX5E_CHANNEL_STATE_XSK flag checked in mlx5e_xsk_wakeup indicates
that XSK queues are open, but not necessarily activated. This check is
not very useful, because:

0. Both XSK setup and netdev state transitions take the same state_lock
mutex, so they can't happen at the same time.

1. If the netdev is up, xsk_is_bound can return true only when
MLX5E_CHANNEL_STATE_XSK is set on the corresponding channel.
mlx5e_xsk_wakeup is only called when xsk_is_bound is true.

2. If the XSK socket is bound, and the netdev is going up or down,
mlx5e_xsk_wakeup can take one of two branches, depending on the return
