+Subject: net: usb: ax88179_178a needs FLAG_SEND_ZLP
+
+From: Jose Alonso <joalonsof@gmail.com>
+
+commit 36a15e1cb134c0395261ba1940762703f778438c upstream.
+
+The extra byte inserted by usbnet.c when
+ (length % dev->maxpacket == 0) is causing problems to device.
+
+This patch sets FLAG_SEND_ZLP to avoid this.
+
+Tested with: 0b95:1790 ASIX Electronics Corp. AX88179 Gigabit Ethernet
+
+Problems observed:
+======================================================================
+1) Using ssh/sshfs. The remote sshd daemon can abort with the message:
+   "message authentication code incorrect"
+   This happens because the tcp message sent is corrupted during the
+   USB "Bulk out". The device calculate the tcp checksum and send a
+   valid tcp message to the remote sshd. Then the encryption detects
+   the error and aborts.
+2) NETDEV WATCHDOG: ... (ax88179_178a): transmit queue 0 timed out
+3) Stop normal work without any log message.
+   The "Bulk in" continue receiving packets normally.
+   The host sends "Bulk out" and the device responds with -ECONNRESET.
+   (The netusb.c code tx_complete ignore -ECONNRESET)
+Under normal conditions these errors take days to happen and in
+intense usage take hours.
+
+A test with ping gives packet loss, showing that something is wrong:
+ping -4 -s 462 {destination}   # 462 = 512 - 42 - 8
+Not all packets fail.
+My guess is that the device tries to find another packet starting
+at the extra byte and will fail or not depending on the next
+bytes (old buffer content).
