Subject: Re: [PATCH net 1/1] qlcnic: Delete existing multicast MAC list
 before adding new

From: Shahed Shaikh <>
Date: Wed, 11 Feb 2015 09:45:24 -0500

> From: Shahed Shaikh <>
> Driver keeps adding multicast addresses without deleting removed MACs and
> worrying about adapters filter limit. This results into actual count of programmed
> multicast addresses get accumulated over the time and overruns the adapter's
> filter limit without putting device in ACCEPT_ALL_MULTI mode. This causes
> newly added multicast traffic to fail after the sequence of addition - deletion
> in certain pattern.
> This issue is seen only when netdev's mcast list count is less than adapters
> mcast filter limit.
> e.g. If adapters multicast filter limit is 38 per function
>      then following sequence would result in multicast traffic failure for
>      newly added MACs.
>      - add less than 38 multicast MACs
>      - remove previously added multicast MACs
>      - add new multicast MACs (less than 38)
