Subject: [PATCH iproute2-next v2 0/2] pretty-print 802.3ad slave state

Print the bond slave 802.3ad state in a human-readable way.
The 802.3ad bond slave actor/partner state definitions are exported
to userspace in the kernel include/uapi (dependent on the related
patch posted to net-next)

rtnetlink sends the bond slave state to userspace, see
 - IFLA_BOND_SLAVE_AD_ACTOR_OPER_PORT_STATE; and
 - IFLA_BOND_SLAVE_AD_PARTNER_OPER_PORT_STATE

and these are only printed as numbers, e.g.,

ad_actor_oper_port_state 15

Add an additional output in ip link show that prints a string describing
the individual 3ad bit meanings.

ad_actor_oper_port_state_str <active,short_timeout,aggregating,in_sync>

JSON output is also supported, the field becomes a json array:

"ad_actor_oper_port_state_str":
	["active","short_timeout","aggregating","in_sync"]

These changes are dependent on a kernel change to uapi/
The following patch is the kernel change sent to net-next:
[PATCH net-next v2] bonding: move 802.3ad port state flags to uapi

v2:
 - address patch format and comments

Andy Roulin (2):
  include/uapi: update bonding kernel header
  iplink: bond: print 3ad actor/partner oper states as strings
