Subject: ip/bond: add lacp active support
X-Git-Tag: v5.15.0~19
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6d0d35bab9f8af48a3f796e2302834db36eda96d;p=thirdparty%2Fiproute2.git

ip/bond: add lacp active support

lacp_active specifies whether to send LACPDU frames periodically.
If set on, the LACPDU frames are sent along with the configured lacp_rate
setting. If set off, the LACPDU frames acts as "speak when spoken to".

v2: use strcmp instead of match for new options.
