SubjectRe: [PATCH net] net: mvpp2: Fix TCAM filter reserved range
From: Maxime Chevallier <>
Date: Mon, 16 Apr 2018 10:07:23 +0200

> Marvell's PPv2 controller has a Packet Header parser, which uses a
> fixed-size TCAM array of filter entries.
> The mvpp2 driver reserves some ranges among the 256 TCAM entries to
> perform MAC and VID filtering. The rest of the TCAM ids are freely usable
> for other features, such as IPv4 proto matching.
> This commit fixes the MVPP2_PE_LAST_FREE_TID define that sets the end of
> the "free range", which included the MAC range. This could therefore allow
> some other features to use entries dedicated to MAC filtering,
> lowering the number of unicast/multicast addresses that could be allowed
> before switching to promiscuous mode.
> Fixes: 10fea26ce2aa ("net: mvpp2: Add support for unicast filtering")
