Hi Dave,

avoiding the need to override the address space limited as in the current
handler.

According to the 8021q standard, the VLAN id range is 1 to 4095.
But in the register_vlan_device function, the range is 1 to 4094,
because ">= VLAN_VID_MASK" is used to determine whether the id
is illegal. This will prevent the creation of the vlan4095 interface:

Good catch. I'm not sure about the fix though. That variable ('addr')
should be a ethernet hardware address; I'm surprised we're accessing
past the 6th byte. The culprit seems to be this, where 'ea' is the

Will fix. Thanks.

Allow the user to configure where on the cable the TDR data should be
retrieved, in terms of first and last sample, and the step between
samples. Also add the ability to ask for TDR data for just one pair.
If this configuration is not provided, it defaults to 0-150m at 1m
intervals for all pairs.
Getting the TDR data requires a large number of MDIO bus
transactions. The number can however be reduced if the page is only
changed once. Add the needed locking to allow this, and make use of
unlocked read/write methods where needed.

The 'pref medium' attribute was moved in iproute2 to be near the prefix
which is where it applies versus after the last nexthop. The nexthop
tests were updated to drop the string from route checking, but it crept
in again with the compat tests.

If expire_nodest_conn=1 and a UDP destination is deleted, IPVS should
also expire all matching connections immiediately instead of waiting for
the next matching packet. This is particulary useful when there are a
lot of packets coming from a few number of clients. Those clients are
likely to match
Hi Julian,
Thanks for getting back to me, that makes sense.
Would you be opposed to trying to expire all UDP connections matching
a deleted destination only if expire_nodest_conn=1?
Even today with `expire_nodest_conn=1`, many packets could be dropped
if there are many requests from a single clie

For nexthop groups, attributes after NHA_GROUP_TYPE are invalid, but
nh_check_attr_group starts checking at NHA_GROUP. The group type defaults
to multipath and the NHA_GROUP_TYPE is currently optional so this has
slipped through so far. Fix the attribute checking to handle suppo

Have print_tm() dump firstuse value along with install, lastuse
and expires.

When a new action is installed, firstuse field of 'tcf_t' is explicitly set
to 0. Value of zero means "new action, not yet used"; as a packet hits the
action, 'firstuse' is stamped with the current jiffies value.
tcf_tm_dump() should return 0 for firstuse if action has not yet been hit.

The compilation warning below reveals that the errors returned from
the sfp_bus_add_upstream() call are not propagated to the callers.
Fix it by returning "ret".
