Subject: [PATCH 4.11 004/150] net: systemport: Fix missing Wake-on-LAN interrupt for SYSTEMPORT Lite

4.11-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Florian Fainelli <f.fainelli@...il.com>


[ Upstream commit d31353cd753c443ace5723d6878a39f393a0c136 ]

On SYSTEMPORT Lite, since we have the main interrupt source in the first
cell, the second cell is the Wake-on-LAN interrupt, yet the code was not
properly updated to fetch the second cell, and instead looked at the
third and non-existing cell for Wake-on-LAN.
