3.3-stable review patch. If anyone has any objections, please let me know.
------------------ From: Rabin Vincent <[email protected]> [ Upstream commit 78fb72f7936c01d5b426c03a691eca082b03f2b9 ] Make CDC EEM recalculate the hard_mtu after adjusting the hard_header_len. Without this, usbnet adjusts the MTU down to 1494 bytes, and the host is unable to receive standard 1500-byte frames from the device. Tested with the Linux USB Ethernet gadget.
