HI Netdev team,
Greetings. We have been monitoring the vrf device approach for l3
isolation from cumulus networks and we are currently interested in validating
it. We have following questions on them and hoping to get answers from
you/concerned team.

Hello,
Does anyone can say what's the difference between smc911 and smsc911 ?
On reading the first comments in each file it seems that there is
overlapping between them:

Eric, please double check my merge work for net/ipv4/udp.c
In net we fixed a soreuseport bug that added a hlist_nulls_add_tail_rcu()
call to net/ipv4/udp.c
And in net-next you converted UDP sockets away from nulls lists.
Therefore I had to add a hlist_add_tail_rcu() implementation to

If macvlan_common_newlink fails in register_netdevice after macvlan_init

A similar problem may exist in the ipvlan driver.

This series of two patches adds the following improvements to the driver:
1) Rework the central SPI read function so that it is compatible with
SPI masters which only support half duplex transfers.
2) Add a device tree binding for the driver.

The following patch adds the required match table for device tree support

Also add the corresponding binding documentation file.

The current spi_read_buf function fails on SPI host masters which
are only half-duplex capable. Splitting the Tx and Rx part solves
this issue.

Add structures for identifiers, locators, and an ila address which
is composed of a locator and identifier and in6_addr can be cast to
