Hi,
Any chance this behaviour gets fixed, with either a new firmware or a
workaround in the kernel ?

Hi,
First pull request for this cycle, and the fix for the pointer issue is
the first patch in it :) Since nobody really has devices with enough
streams where this matters, it was pretty harmless though.
Other than that, there are a few fixes all over - let me know if you
see any issues.

In the next patch, we're going to add a way to access the underlying

Hi!
This patchset completes the set of available Address Translation Unit

These Marvell switches have 4 operations to flush or (re)move, all or

The first 3 patches introduce a generic _mv88
Other ATU commands need to write the ATU data register. To ease the

It is a prep work to get dst freeing from fib tree undergo
a rcu grace period.
The following is a common paradigm:
if (ip6_del_rt(rt))
dst_free(rt)
which means, if rt cannot be deleted from the fib tree, dst_free(rt) now.
1. We don't know the ip6_del_rt(rt) failure is because it
was no
It is a prep work to fix the dst_entry refcnt bugs in ip6_tunnel.
This patch refactors some common init codes used by both
ip6gre_tunnel_init and ip6gre_tap_init.

It is a prep work to fix the dst_entry refcnt bugs in
ip6_tunnel.
This patch rename:
1. ip6_tnl_dst_check() to ip6_tnl_dst_get() to better
reflect that it will take a dst refcnt in the next patch.
2. ip6_tnl_dst_store() to ip6_tnl_dst_set() to have a more
conventional name matching with ip6_
This patch uses a seqlock to ensure consistency between idst->dst and
idst->cookie. It also makes dst freeing from fib tree to undergo a
