Message-Id: <20070103180513.45D4D3AA7EE@silver.suse.cz>

Subject: [PATCH 5/12] d80211: Turn PHYmode list from an array into a linked list
From: Michael Buesch <mb@...sch.de>
This turns the PHY-modes list into a linked list.
The advantage is that drivers can add modes dynamically, as they probe
them and don't have to settle to a given arraysize at the beginning
of probing.
