Subject: [patch net-next v2 00/28] bonding/team offload + mlxsw implementation

From: Jiri Pirko <jiri@...lanox.com>

This patchset introduces needed infrastructure for link aggregation
offload - for both team and bonding. It also implements the offload
in mlxsw driver.

Particulary, this patchset introduces possibility for upper driver
(bond/team/bridge/..) to pass type-specific info down to notifier listeners.
Info is passed along with NETDEV_CHANGEUPPER/NETDEV_PRECHANGEUPPER
notifiers. Listeners (drivers of netdevs being enslaved) can react
accordingly.

Other extension is for run-time use. This patchset introduces
new netdev notifier type - NETDEV_CHANGELOWERSTATE. Along with this
notification, the upper driver (bond/team/bridge/..) can pass some
information about lower device change, particulary link-up and
TX-enabled states. Listeners (drivers of netdevs being enslaved)
can react accordingly.

The last part of the patchset is implementation of LAG offload in mlxsw,
using both previously introduced infrastructre extensions.

Note that bond-speficic (and ugly) NETDEV_BONDING_INFO used by mlx4
can be removed and mlx4 can use the extensions this patchset adds.
I plan to convert it and get rid of NETDEV_BONDING_INFO in
a follow-up patchset.
