In iwl_pcie_ctxt_info_gen3_init there are cases that the allocated dma
memory is leaked in case of error.
DMA memories prph_scratch, prph_info, and ctxt_info_gen3 are allocated
and initialized to be later assigned to trans_pcie. But in any error case
before such assignment the allocated memories should be released.
First of such error cases happens when iwl_pcie_init_fw_sec fails.
Current implementation correctly releases prph_scratch. But in two
sunsequent error cases where dma_alloc_coherent may fail, such
releases are missing.
This commit adds release for prph_scratch when allocation for
prph_info fails, and adds releases for prph_scratch and prph_info when
allocation for ctxt_info_gen3 fails.

We got a crash in iwl_trans_pcie_get_cmdlen(), while the TFD was
being accessed to sum up the lengths.
We want to access the TFD here, which is the information for the
hardware. We always only allocate 32 buffers for the cmd queue,
but on newer hardware (using TFH) we can also allocate only a
shorter hardware array, also only 32 TFDs. Prior to the TFH, we
had to allocate a bigger TFD array but would make those point to
a smaller set of buffers.
Additionally, now max_tfd_queue_size is up to 65536, so we can
access *way* out of bounds of a really only 32-entry array, so
it crashes.
Fix this by making the TFD index depend on which hardware we are
using right now.
While changing the calculation, also fix it to not use void ptr
arithmetic, but cast to u8 * before.

Consider the following flow:
1. Driver starts to sync the rx queues due to a delba.
mvm->queue_sync_cookie=1.
This rx-queues-sync is synchronous, so it doesn't increment the
cookie until all rx queues handle the notification from FW.
2. During this time, driver starts to sync rx queues due to nssn sync
required.
The cookie's value is still 1, but it doesn't matter since this
rx-queue-sync is non-synchronous so in the notification handler the
cookie is ignored.
What _does_ matter is that this flow increments the cookie to 2
immediately.
Remember though that the FW won't start servicing this command until
it's done with the previous one.
3. FW is still handling the first command, so it sends a notification
with internal_notif->sync=1, and internal_notif->cookie=0, which
triggers a WARN_ONCE.
The solution for this race is to only use the mvm->queue_sync_cookie in
case of a synchronous sync-rx-queues. This way in step 2 the cookie's
value won't change so we avoid the WARN.
The commit in the "fixes" field is the first commit to introduce
non-synchronous sending of this command to FW.

of autoneg is enabled, or the forced mode if autoneg is disabled.
This ensures that phylib's software state always tracks the hardware

xennet_fill_frags() uses ~0U as return value when the sk_buff is not able
to cache extra fragments. This is incorrect because the return type of
xennet_fill_frags() is RING_IDX and 0xffffffff is an expected value for
ring buffer index.
In the situation when the rsp_cons is approaching 0xffffffff, the return
value of xennet_fill_frags() may become 0xffffffff which xennet_poll() (the
caller) would regard as error. As a result, queue->rx.rsp_cons is set
incorrectly because it is updated only when there is error. If there is no
error, xennet_poll() would be responsible to update queue->rx.rsp_cons.
Finally, queue->rx.rsp_cons would point to the rx ring buffer entries whose
queue->rx_skbs[i] and queue->grant_rx_ref[i] are already cleared to NULL.
This leads to NULL pointer access in the next iteration to process rx ring
buffer entries.
The symptom is similar to the one fixed in
commit 00b368502d ("xen-netfront: do not assume sk_buff_head list is
empty in error handling").
This patch changes the return type of xennet_fill_frags() to indicate
whether it is successful or failed. The queue->rx.rsp_cons will be
always updated inside this function.

Although some XGMAC setups support frames larger than DMA size, some of
them may not. As we can't know before-hand which ones support let's use
the maximum DMA buffer size in the Jumbo Tests.
User can always reconfigure the MTU to achieve larger frames.

Since commit b8ef7020d6 ("net: stmmac: add support for hash table size
128/256 in dwmac4"), we can detect the Hash Table dinamically.
Let's implement this feature in XGMAC cores and fix possible setups that
don't support the maximum size for Hash Table.

Some setups may not have all Unicast addresses filters available. Let's
check this before trying to setup filters.
