If only I could figure out how to use the command.
Allow TTL propagation from IP packets to MPLS packets to be
configured. Add a new optional LWT attribute, MPLS_IPTUNNEL_TTL, which
allows the TTL to be set in the resulting MPLS packet, with the value
of 0 having the semantics of enabling propagation of the TTL from the
IP header (i.e. non-zero val
Provide the ability to control on a per-route basis whether the TTL
value from an MPLS packet is propagated to an IPv4/IPv6 packet when

It is sometimes desirable to present an MPLS transport network as a

diagnosing failures. An example of where confusion can be generated is
when addresses used in the provider network overlap with addresses in

Hi,
One minor comment:
The return type of xge_init_hw() should be changed to be void, as
the method xge_port_reset() always returns 0; and also the return type
of xge_port_reset() should be changed to be void, it never fails; see
in [PATCH v4 net-next 3/6] drivers: net: xgene-v2: Add ethernet
har
when all map elements are pre-allocated one cpu can delete and reuse htab_elem
while another cpu is still walking the hlist. In such case the lookup may
miss the element. Convert hlist to hlist_nulls to avoid such scenario.
When bucket lock is taken there is no need to take such precautions,
so onl
when htab_elem is removed from the bucket list the htab_elem.hash_node.next
field should not be overridden too early otherwise we have a tiny race window
between lookup and delete.
The bug was discovered by manual code analysis and reproducible
only with explicit udelay() in lookup_elem_raw().
Fix
Two bpf hashtable fixes. See individual patches for details.
