Igor Russkikh - Dec. 6, 2018, 3:02 p.m.
From: Dmitry Bogdanov <dmitry.bogdanov@aquantia.com>

Now RSS indirection table is initialized before setting up the number of
hw queues, consequently the table may be filled by non existing queues.
This patch moves the initialization when the number of hw queues is
known.
