Subject: [PATCH] drivers/net/bonding: Adjust constant name

From: Julia Lawall <[email protected]>

AD_SHORT_TIMEOUT and AD_STATE_LACP_ACTIVITY have the same value, but
AD_STATE_LACP_ACTIVITY better reflects the intended semantics.

The semantic match that finds this problem is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@@
struct port_params p;
@@
* p.port_state |= AD_SHORT_TIMEOUT
// </smpl>

AD_SHORT_TIMEOUT and AD_STATE_LACP_ACTIVITY have the same value, but
AD_STATE_LACP_ACTIVITY better reflects the intended semantics.

[ J adds: AD_STATE_LACP_ACTIVITY is a value defined by the standard, and
should be set here in accordance with 802.3ad 43.4.12; AD_SHORT_TIMEOUT
is a constant specific to the Linux 802.3ad implementation that happens
to have the same value ]

Applied.
