+Subject: [PATCH] b43: fix support for 14e4:4321 PCI dev with BCM4321 chipset
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+It seems Broadcom released two devices with conflicting device id. There
+are for sure 14e4:4321 PCI devices with BCM4321 (N-PHY) chipset, they
+can be found in routers, e.g. Netgear WNR834Bv2. However, according to
+Broadcom public sources 0x4321 is also used for 5 GHz BCM4306 (G-PHY).
+It's unsure if they meant PCI device id, or "virtual" id (from SPROM).
+To distinguish these devices lets check PHY type (G vs. N).
