virtio: Revert "virtio: find_vqs() add arg sizes"

2022-08-16T05:40:24+00:00

This reverts commit a10fba0377145fccefea4dc4dd5915b7ed87e546: the
proposed API isn't supported on all transports but no
effort was made to address this.

It might not be hard to fix if we want to: maybe just
rename size to size_hint and make sure legacy
transports ignore the hint.

But it's not sure what the benefit is in any case, so
let's drop it.

virtio: find_vqs() add arg sizes

2022-08-11T08:06:40+00:00

find_vqs() adds a new parameter sizes to specify the size of each vq
vring.

NULL as sizes means that all queues in find_vqs() use the maximum size.
A value in the array is 0, which means that the corresponding queue uses
the maximum size.

In the split scenario, the meaning of size is the largest size, because
it may be limited by memory, the virtio core will try a smaller size.
And the size is power of 2.

virtio: record the maximum queue num supported by the device.

2022-08-11T08:06:38+00:00

virtio-net can display the maximum (supported by hardware) ring size in
ethtool -g eth0.

When the subsequent patch implements vring reset, it can judge whether
the ring size passed by the driver is legal based on this.

platform/mellanox: mlxreg-lc: Fix error flow and extend verbosity

2022-07-28T18:38:08+00:00

Fix error flow:
- Clean-up client object in case of probing failure.
- Prevent running remove routine in case of probing failure.
  Probing and removing are invoked by hotplug events raised upon line
  card insertion and removing. If probing procedure failed all data is
  cleared and there is nothing to do in remove routine.

2022-06-27T07:38:56+00:00

This should return PTR_ERR() instead of IS_ERR().  Also "dev->client"
has been set to NULL by this point so it returns 0/success so preserve
the error code earlier.
