The modular driver supports only one card, just like the built-in
driver.
Note that this limitation is a problem which affects all Nubus card
drivers, because they have to do all their own bus matching, because
Nubus still lacks the necessary driver model support.

Allow to change the replay threshold (XFRMA_REPLAY_THRESH) and expiry

Most important part of this patchset is the introducing of what I call

This change focus on improving the speed of object freeing in the
"slowpath" of kmem_cache_free_bulk.
The calls slab_free (fastpath) and __slab_free (slowpath) have been
extended with support for bulk free, which amortize the overhead of
the (locked) cmpxchg_double.
To use the new bulking feature
Implement a basic approach of bulking in the SLAB allocator. Simply
use local_irq_{disable,enable} and call single alloc/free in a loop.
This simple implementation approach is surprising fast.
Notice the normal SLAB fastpath is: 96 cycles (24.119 ns). Below table

Add support for filtering neighbor dumps by master device by adding
the NDA_MASTER attribute to the dump request. A new netlink flag,
NLM_F_DUMP_FILTERED, is added to indicate the kernel supports the
request and output is filtered as requested.

Store tunnel protocol (AF_INET or AF_INET6) in sw_flow_key. This field now
also acts as an indicator whether the flow contains tunnel data (this was
previously indicated by tun_key.u.ipv4.dst being set but with IPv6 addresses
in an union with IPv4 ones this won't work anymore).
The new field was a
This builds on the previous work that added IPv6 support to lwtunnels and
adds IPv6 tunneling support to ovs; it is now pretty straightforward.
To use IPv6 tunneling, there needs to be a metadata based tunnel net_device
created and added to the ovs bridge. Currently, only vxlan is supported by
th
Add netlink attributes for IPv6 tunnel addresses. This enables IPv6 support
for tunnels.
When compat code for tunnel configuration is used, IPv6 tun_info will be
rejected by ovs_tunnel_get_egress_info. As the consequence, only the new way
of tunnel config supports IPv6.

Because of the default 0 value of ret in dsa_slave_port_attr_set, a
driver may return -EOPNOTSUPP from the commit phase of a STP state,
which triggers a WARN() from switchdev.
This happened on a 6185 switch which does not support hardware bridging.

Test interrupts fails if not all completion vectors called
request_irq. This case can happen if only mlx4_en loads and
we have more completion vectors than rx rings.
