net/mlx5e: Reduce the size of icosq_str

[ Upstream commit dce94142842e119b982c27c1b62bd20890c7fd21 ]

icosq_str size is unnecessarily too long, and it causes a build warning
-Wformat-truncation with W=1. Looking closely, It doesn't need to be 255B,
hence this patch reduces the size to 32B which should be more than enough
to host the string: "ICOSQ: 0x%x, ".

While here, add a missing space in the formatted string.

This fixes the following build warning:

net/mlx5e: RX, Defer page release in striding rq for better recycling

Currently, for striding RQ, fragmented pages from the page pool can
get released in two ways:

1) In the mlx5e driver when trimming off the unused fragments AND the
associated skb fragments have been released. This path allows
recycling of pages to the page pool cache (allow_direct == true).

2) On the skb release path (last fragment release), which
will always release pages to the page pool ring
(allow_direct == false).

Whichever is releasing the last fragment will be decisive on
where the page gets released: the cache or the ring. So we
obviously want to maximize for doing the release from 1.

This patch does that by deferring the release of page fragments
right before requesting new ones from the page pool. Extra care
needs to be taken for the corner cases:

* On first call, make sure that release is not called. The
skip_release_bitmap is used for this purpose.

* On rq shutdown, make sure that all wqes that were not
in the linked list are released.

For a single ring, single core, default MTU (1500) TCP stream
test the number of pages allocated from the cache directly
(rx_pp_recycle_cached) increases from 31 % to 98 %:

+----------------------------------------------+
| Page Pool stats (/sec) | Before | After |
+-------------------------+---------+----------+
|rx_pp_alloc_fast | 2137754 | 2261033 |
|rx_pp_alloc_slow | 47 | 9 |
|rx_pp_alloc_empty | 47 | 9 |
|rx_pp_alloc_refill | 23230 | 819 |
|rx_pp_alloc_waive | 0 | 0 |
|rx_pp_recycle_cached | 672182 | 2209015 |
|rx_pp_recycle_cache_full | 1789 | 0 |
|rx_pp_recycle_ring | 1485848 | 52259 |
|rx_pp_recycle_ring_full | 3003 | 584 |
+----------------------------------------------+

With this patch, the performance in striding rq for the above test is
back to baseline.

net/mlx5e: Add XSK RQ state flag for RQ devlink health diagnostics

Currently RQ health diagnostics doesn't inform the user whether an RQ
is an XSK RQ or not.

Address this, by adding XSK state flag to RQ SW state enum in core/en.h.
XSK will be '1' if current RQ is an XSK RQ, and it will be '0' if it's
not.

In this example below, it can be seen that XSK field value is '1' since
xdpsock program have been attached to channel 0 before issuing the
devlink query command:

One of the parameters that is retrieved/printed as a response to

It's printed as a bitmap decimal number. Printing it as bitmap is
problematic and non informative.

In addition User can't count on SW state without accessing the kernel

This patch prints RQ SW state in a textual representation, as a key:
value pairs, where disabled rq states will appear as '0' and enabled

net/mlx5e: Disable softirq in mlx5e_activate_rq to avoid race condition

When the driver activates the channels, it assumes NAPI isn't running
yet. mlx5e_activate_rq posts a NOP WQE to ICOSQ to trigger a hardware
interrupt and start NAPI, which will run mlx5e_alloc_rx_mpwqe and post
UMR WQEs to ICOSQ to be able to receive packets with striding RQ.

Unfortunately, a race condition is possible if NAPI is triggered by
something else (for example, TX) at a bad timing, before
mlx5e_activate_rq finishes. In this case, mlx5e_alloc_rx_mpwqe may post
UMR WQEs to ICOSQ, and with the bad timing, the wqe_info of the first
UMR may be overwritten by the wqe_info of the NOP posted by
mlx5e_activate_rq.

The consequence is that icosq->db.wqe_info[0].num_wqebbs will be changed
from MLX5E_UMR_WQEBBS to 1, disrupting the integrity of the array-based
linked list in wqe_info[]. mlx5e_poll_ico_cq will hang in an infinite
loop after processing wqe_info[0], because after the corruption, the
next item to be processed will be wqe_info[1], which is filled with
zeros, and `sqcc += wi->num_wqebbs` will never move further.

This commit fixes this race condition by using async_icosq to post the
NOP and trigger the interrupt. async_icosq is always protected with a
spinlock, eliminating the race condition.

XSK can be opened and closed while channels are active, so a new mutex

recovery deactivates and reactivates XSKRQ, so any parallel change in
XSK state would break consistency. As the regular RQ is running, it's
not enough to just flush the recovery work, because it can be
