+Subject: phylib: add the ICPlus IP175C PHY driver
+X-Git-Tag: v2.6.23-rc1~1201^2~58
+X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Ftorvalds%2Flinux-2.6.git;a=commitdiff_plain;h=0cefeebaf3da39d768bffcf62460fe2088e824ef
+
+phylib: add the ICPlus IP175C PHY driver
+
+The ICPlus IP175C sports a 100Mbit/s 4-port switch in addition
+to a dedicated 100Mbit/s WAN port.
