net: introduce ethernet teaming device
This patch introduces new network device called team. It supposes to be
very fast, simple, userspace-driven alternative to existing bonding
driver.
Userspace library called libteam with couple of demo apps is available
here:
https://github.com/jpirko/libteam
Note it's still in its dipers atm.
team<->libteam use generic netlink for communication. That and rtnl
suppose to be the only way to configure team device, no sysfs etc.
Python binding of libteam was recently introduced.
Daemon providing arpmon/miimon active-backup functionality will be
introduced shortly. All what's necessary is already implemented in
kernel team driver.
v7->v8:
- check ndo_ndo_vlan_rx_[add/kill]_vid functions before calling
them.
- use dev_kfree_skb_any() instead of dev_kfree_skb()
v6->v7:
- transmit and receive functions are not checked in hot paths.
That also resolves memory leak on transmit when no port is
present
v5->v6:
- changed couple of _rcu calls to non _rcu ones in non-readers
v4->v5:
- team_change_mtu() uses team->lock while travesing though port
list
- mac address changes are moved completely to jurisdiction of
userspace daemon. This way the daemon can do FOM1, FOM2 and
possibly other weird things with mac addresses.
Only round-robin mode sets up all ports to bond's address then
enslaved.
- Extended Kconfig text
v3->v4:
- remove redundant synchronize_rcu from __team_change_mode()
- revert "set and clear of mode_ops happens per pointer, not per
byte"
- extend comment of function __team_change_mode()
v2->v3:
- team_change_mtu() uses rcu version of list traversal to unwind
- set and clear of mode_ops happens per pointer, not per byte
- port hashlist changed to be embedded into team structure
- error branch in team_port_enter() does cleanup now
- fixed rtln->rtnl
v1->v2:
- modes are made as modules. Makes team more modular and
extendable.
- several commenters' nitpicks found on v1 were fixed
- several other bugs were fixed.
- note I ignored Eric's comment about roundrobin port selector
as Eric's way may be easily implemented as another mode (mode
"random") in future.
