Subject: [PATCH net 2/2] net: mvpp2: prs: Use the correct helpers when removing all VID filters
Date: Tue, 11 Jun 2019 11:51:43 +0200	[thread overview]
Message-ID: <20190611095143.2810-3-maxime.chevallier@bootlin.com> (raw)
In-Reply-To: <20190611095143.2810-1-maxime.chevallier@bootlin.com>

When removing all VID filters, the mvpp2_prs_vid_entry_remove would be
called with the TCAM id incorrectly used as a VID, causing the wrong
TCAM entries to be invalidated.

Fix this by directly invalidating entries in the VID range.

Fixes: 56beda3db602 ("net: mvpp2: Add hardware offloading for VLAN filtering")
Suggested-by: Yuri Chipchev <yuric@marvell.com>
