[PATCH net-next 0/5] net/mlx5: Convert mlx5 to netdev instance locking

[Tariq Toukan <tariqt@nvidia.com>]

Hi,

This series by Cosmin converts mlx5 to use the recently added netdev
instance locking scheme.

Find detailed description by Cosmin below [1].

Regards,

mlx5 manages multiple netdevices, from basic Ethernet to Infiniband
netdevs. This patch series converts the driver to use netdev instance
locking for everything in preparation for TCP devmem Zero Copy.

Because mlx5 is tightly coupled with the ipoib driver, a series of
changes first happen in ipoib to allow it to work with mlx5 netdevs that
use instance locking:

IB/IPoIB: Enqueue separate work_structs for each flushed interface
IB/IPoIB: Replace vlan_rwsem with the netdev instance lock
IB/IPoIB: Allow using netdevs that require the instance lock

A small patch then avoids dropping RTNL during firmware update:
net/mlx5e: Don't drop RTNL during firmware flash

The main patch then converts all mlx5 netdevs to use instance locking:
net/mlx5e: Convert mlx5 netdevs to instance locking
