Date: Wed, 15 Feb 2012 14:47:39 +0000 From: Toby Gray <toby.gray@...lvnc.com> To: Toby Gray <tg@...lvnc.com>, Oliver Neukum <oliver@...kum.name>, Greg Kroah-Hartman <gregkh@...uxfoundation.org>, linux-usb@...r.kernel.org Cc: netdev@...r.kernel.org, alexey.orishko@...il.com, Toby Gray <toby.gray@...lvnc.com> Subject: [PATCH 3/5] usb: usbnet: Allow drivers using usbnet to specify maximum packet size The usbnet driver always attempts to set dev->maxpacket from the out endpoint. For this to function correctly it relies on the alternate setting containg the bulk out endpoint to be selected. This isn't necessarily always the case. This change allows drivers that make use of usbnet to specify the value for dev->maxpacket themselves.
