Subject: [net-next 03/14] ice: fix the vsi_id mask to be 10 bit for set_rss_lut
Date: Sat, 1 Aug 2020 09:17:51 -0700 [thread overview]
Message-ID: <20200801161802.867645-4-anthony.l.nguyen@intel.com> (raw)
In-Reply-To: <20200801161802.867645-1-anthony.l.nguyen@intel.com>
From: Kiran Patil <kiran.patil@intel.com>
set_rss_lut can fail due to incorrect vsi_id mask. vsi_id is 10 bit
but mask was 0x1FF whereas it should be 0x3FF.
For vsi_num >= 512, FW set_rss_lut can fail with return code
EACCESS (VSI ownership issue) because software was providing
incorrect vsi_num (dropping 10th bit due to incorrect mask) for
set_rss_lut admin command
