dsa: Add support for the ethernet switch on the ESPRESSObin
This set of patches adds support for the Marvell Ethernet Topaz switch
family (88E6141/88E6341) which is found on the ESPRESSObin. With this
series the network is usable on this board.
As usual, I rebased the series on the very last net-next/master. In
this series there is no temperature support which need some patches
form Andrew Lunn.
As soon as Andrew Lunn will post the needed patch I will send a patch
to enable the temperature support.
Changelog:
v6 -> v7:
- rebased on net-next/master (5b8784aaf2)
- Fixed the wrong age time coeff from 15s to 3.75s.
- Remove support for temperature sensor
v5 -> v6:
- rebased on net-next/master (d140199af5)
- Fix the redundant check on mv88e6xxx_6341_family (reported by Julia
Lawall)
- Add support for the 88E6141

Some Marvell ethernet switches have internal ethernet transceivers with

of ports or its value might be different than the associated port number.
This is for example the case for MV88E6341 that has 6 ports and internal
Port 1 to Port4 PHYs mapped at SMI addresses from 0x11 to 0x14.

net: dsa: Port mirroring support
This patch series adds support for port mirroring in the two
Broadcom switch drivers. The major part of the functional are actually with
the plumbing between tc and the drivers.
Changes in v5:
- Added Jiri's Reviewed-by tag to first patch
- rebase against latest net-next/master after bcm_sf2 CFP series
Changes in v4:
- rebased against latest net-next/master after Vivien's changes
Changes in v3:
- removed multiline comments from added structures
- simplify error handling in dsa_slave_add_cls_matchall
Changes in v2:
- fixed filter removal logic to disable the ingress or egress mirroring
when there are no longer ports being monitored in ingress or egress
- removed a stray list_head in dsa_port structure that is not used
Tested using the two iproute2 examples:
tc qdisc add dev eth1 handle ffff: ingress
tc filter add dev eth1 parent ffff: \
matchall skip_sw \
action mirred egress mirror \
dev eth2
tc qdisc add dev eth1 handle 1: root prio
tc filter add dev eth1 parent 1: \
matchall skip_sw \

Packets arriving in a VRF currently are delivered to UDP sockets that
aren't bound to any interface. TCP defaults to not delivering packets
arriving in a VRF to unbound sockets. IP route lookup and socket
transmit both assume that unbound means using the default table and
UDP applications that haven't been changed to be aware of VRFs may not
function correctly in this case since they may not be able to handle
overlapping IP address ranges, or be able to send packets back to the
original sender if required.
So add a sysctl, udp_l3mdev_accept, to control this behaviour with it
being analgous to the existing tcp_l3mdev_accept, namely to allow a
process to have a VRF-global listen socket. Have this default to off
as this is the behaviour that users will expect, given that there is
no explicit mechanism to set unmodified VRF-unaware application into a
default VRF.

Currently the retransmission stats are not incremented if the
retransmit fails locally. But we always increment the other packet
counters that track total packet/bytes sent. Awkwardly while we
don't count these failed retransmits in RETRANSSEGS, we do count
them in FAILEDRETRANS.
If the qdisc is dropping many packets this could under-estimate
TCP retransmission rate substantially from both SNMP or per-socket
TCP_INFO stats. This patch changes this by always incrementing
retransmission stats on retransmission attempts and failures.
Another motivation is to properly track retransmists in
SCM_TIMESTAMPING_OPT_STATS. Since SCM_TSTAMP_SCHED collection is
triggered in tcp_transmit_skb(), If tp->total_retrans is incremented
after the function, we'll always mis-count by the amount of the
latest retransmission.

The PHY driver is attached only when the driver calls

The interface can be brought down, a new PHY driver can be loaded,

to display information about the attached driver.
