This is a note to let you know that I have just added a patch titled net: fix endian check warning in etherdevice.h 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 3.16.7-ckt18. If you, or anyone else, feels it should not be added to this tree, please reply to this email.

Sparse builds have been warning for a really long time now that etherdevice.h has a conversion that is unsafe. include/linux/etherdevice.h:79:32: warning: restricted __be16 degrades to integer This code change fixes the issue and generates the exact same assembly before/after (checked on x86_64) Fixes: 2c722fe1c821 (etherdevice: Optimize a few is_<foo>_ether_addr functions) Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> CC: Joe Perches <joe@perches.com> Signed-off-by: David S.
