+Subject: [PATCH] net: Fix for packets being rejected in the xHCI controller's
+ ring buffer
+
+When a packet larger than MTU arrives in Linux from the modem, it is
+discarded with -EOVERFLOW error (Babble error).
+
+This is seen on USB3.0 and USB2.0 buses.
+
+This is because the MRU (Max Receive Size) is not a separate entity
+from the MTU (Max Transmit Size), and the received packets can be
+larger than those transmitted.
+
+Following the babble error, there was an endless supply of zero-length
+URBs that were rejected with -EPROTO (increasing the rx input error
+counter each time).
+
+This is only seen on USB3.0. These continue to come ad infinitum until
+the modem is shut down.
+
+There appears to be a bug in the core USB handling code in Linux that
+doesn't deal with network MTUs smaller than 1500 bytes well.
+
+By default, the dev->hard_mtu (the real MTU) is in lockstep with
+dev->rx_urb_size (essentially an MRU), and the latter is causing
+trouble.
+
+This has nothing to do with the modems; the issue can be reproduced by
+getting a USB-Ethernet dongle, setting the MTU to 1430, and pinging
+with size greater than 1406.
+
+Signed-off-by: Seija Kijin <doremylover123@gmail.com>
+
+Co-Authored-By: TarAldarion <gildeap@tcd.ie>
+
+Upstream-Status: Inappropriate [other]
+  Workaround for the babble issue, breaks qmap link aggregation that uses
+  datagram sizes bigger than 1504. qmap link aggregation requires datagram
+  sizes of 4096, 16384 bytes and so on, depending on the radio.
+  mPower and mLinux do not use qmap link aggregation, but set the MTU based
+  on the value reported by the radio (provider-specific). This patch sets
+  "almost-MRU" to a high and fixed value, and should be enough for our needs.
+  See GP-2221 for details.
