mlx5-updates-2022-05-09
1) Gavin Li, adds exit route from waiting for FW init on device boot and
increases FW init timeout on health recovery flow
2) Support 4 ports HCAs LAG mode
Mark Bloch Says:
================
This series adds to mlx5 drivers support for 4 ports HCAs.
Starting with ConnectX-7 HCAs with 4 ports are possible.
As most driver parts aren't affected by such configuration most driver
code is unchanged.
Specially the only affected areas are:
- Lag
- Devcom
- Merged E-Switch
- Single FDB E-Switch
Lag was chosen to be converted first. Creating hardware LAG when all 4
ports are added to the same bond device.
Devom, merge E-Switch and single FDB E-Switch, are marked as supporting
only 2 ports HCAs and future patches will add support for 4 ports HCAs.
In order to activate the hardware lag a user can execute the:
ip link add bond0 type bond
ip link set bond0 type bond miimon 100 mode 2
ip link set eth2 master bond0
ip link set eth3 master bond0
ip link set eth4 master bond0
ip link set eth5 master bond0
Where eth2, eth3, eth4 and eth5 are the PFs of the same HCA.

The commit a69755b187 ("xtensa simdisk: switch to proc_create_data()")
split read operation into two parts, first retrieving the path when it's
non-null and second retrieving the trailing '\n'. However when the path
is non-null the first simple_read_from_buffer updates ppos, and the
second simple_read_from_buffer returns 0 if ppos is greater than 1 (i.e.
almost always). As a result reading from that proc file is almost always
empty.
Fix it by making a temporary copy of the path with the trailing '\n' and
using simple_read_from_buffer on that copy.

Logged attribute intents only have set and remove types - there is
no separate intent type for a replace operation. We should have a
separate type for a replace operation, as it needs to perform
operations that neither SET or REMOVE can perform.
Add this type to the intent items and rearrange the deferred
operation setup to reflect the different operations we are
performing.

The problem is related to the breakdown of attribute addition in
xfs_attr_set_iter() and how it is called from deferred operations.
When we have a pure leaf xattr insert, we add the xattr to the leaf
and set the next state to XFS_DAS_FOUND_LBLK and return -EAGAIN.
This requeues the xattr defered work, rolls the transaction and
runs xfs_attr_set_iter() again. This then checks the xattr for
being remote (it's not) and whether a replace op is being done (this
is a create op) and if neither are true it returns without having
done anything.
xfs_xattri_finish_update() then unconditionally sets the transaction
dirty, and the deferops finishes and returns to __xfs_trans_commit()
which sees the transaction dirty and tries to commit it by calling
xlog_cil_commit(). The transaction is empty, and then the assert
fires if this happens when the CIL is empty.
This patch addresses the structure of xfs_attr_set_iter() that
requires re-entry on leaf add even when nothing will be done. This
gets rid of the trailing empty transaction and so doesn't trigger
the XFS_TRANS_DIRTY assignment in xfs_xattri_finish_update()
incorrectly. Addressing that is for a different patch.

Currently, upon virtual interface creation, wfx_add_interface() stores
a reference to the corresponding struct ieee80211_vif in private data,
for later usage. This is not needed when using the container_of
construct. This construct already has all the info it needs to retrieve
the reference to the corresponding struct from the offset that is
already available, inherent in container_of(), between its type and
member inputs (struct ieee80211_vif and drv_priv, respectively).
Remove vif (which was previously storing the reference to the struct
ieee80211_vif) from the struct wfx_vif, define a function
wvif_to_vif(wvif) for container_of(), and replace all wvif->vif with
the newly defined container_of construct.

is exposed to the OS. If it is, then it removes the device from the OS and
