This is a note to let you know that I have just added a patch titled net: eth: altera: fix napi poll_list corruption to the linux-3.16.y-queue branch of the 3.16.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.16.y-queue This patch is scheduled to be released in version 3.19.8-ckt9.

For more information about the 3.16.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From 02eaeb252c09fffa484b25a40d74d2703ae3dde4 Mon Sep 17 00:00:00 2001 From: Atsushi Nemoto <nemoto@toshiba-tops.co.jp> Date: Wed, 2 Sep 2015 17:49:29 +0900 Subject: net: eth: altera: fix napi poll_list corruption [ Upstream commit 4548a697e4969d695047cebd6d9af5e2f6cc728e ] tse_poll() calls __napi_complete() with irq enabled. This leads napi poll_list corruption and may stop all napi drivers working. Use napi_complete() instead of __napi_complete().
