Subject: net: mvpp2: do not sleep in set_rx_mode
Patch-mainline: v4.14-rc7
Git-commit: 239dd4ee4838523419ad16e05b16a2003b71d317
References: bsc#1098633
This patch replaces GFP_KERNEL by GFP_ATOMIC to avoid sleeping in the
ndo_set_rx_mode() call which is called with BH disabled.
Fixes: 3f518509dedc ("ethernet: Add new driver for Marvell Armada 375 network unit")
