[PATCH v2 07/13] net/ionic: fix RSS query routine

[Andrew Boyer <andrew.boyer@amd.com>]

From: Akshay Dorwat <akshay.dorwat@amd.com>

The routine that copies out the RSS config can't use memcpy() because
'reta_conf->reta' is an array of uint16_t while 'lif->rss_ind_tbl' is
an array of uint8_t. Instead, copy the values individually.

Fixes: 22e7171bc63b ("net/ionic: support RSS")
