| |
2.6.27-stable review patch. If anyone has any objections, please let us know.
------------------
From: Bjørn Mork <bjorn@mork.no>
commit cac477e8f1038c41b6f29d3161ce351462ef3df7 upstream.
The Ericsson F3507g wireless broadband module provides a CDC Ethernet compliant interface, but identifies it as a "Mobile Direct Line" CDC subclass, thereby preventing the CDC Ethernet class driver from picking it up. This patch adds the device id to cdc_ether.c as a workaround.
Ericsson has provided a "class" driver for this device: http://kerneltrap.org/mailarchive/linux-net/2008/10/28/3832094 But closer inspection of that driver reveals that it adds little more than duplication of code from cdc_ether.c. See also http://marc.info/?l=linux-usb&m=123334979706403&w=2
