Subject: [PATCH 20/22] ec/dell/mec5035: Add command to enable/disable radios
|
|
|
|
These were determined by sniffing the LPC bus while toggling the
|
|
hardware wireless switch on the Latitude E6400. To differentiate devices
|
|
options in the vendor BIOS to change which radios the switch controlled
|
|
were used.
