2017-04-03net: usbnet: support 64bit statsGreg Ungerer17-4/+69
Add support for the net stats64 counters to the usbnet core. With that in place put the hooks into every usbnet driver to use it. This is a strait forward addition of 64bit counters for RX and TX packet and byte counts. It is done in the same style as for the other net drivers that support stats64. Note that the other stats fields remain as 32bit sized values (error counts, etc). The motivation to add this is that it is not particularly difficult to get the RX and TX byte counts to wrap on 32bit platforms.

2017-04-03vxlan: fix ND proxy when skb doesn't have transport header offsetVincent Bernat1-14/+15
When an incoming frame is tagged or when GRO is disabled, the skb handled to vxlan_xmit() doesn't contain a valid transport header offset. This makes ND proxying fail. We combine two changes: replace use of skb_transport_offset() and ensure the necessary amount of skb is linear just before using it: - In vxlan_xmit(), when determining if we have an ICMPv6 neighbor discovery packet, just check if it is an ICMPv6 packet and rely on neigh_reduce() to do more checks if this is the case. The use of pskb_may_pull() is replaced by skb_header_pointer() for just the IPv6 header. - In neigh_reduce(), add pskb_may_pull() for IPv6 header and neighbor discovery message since this was removed from vxlan_xmit(). Replace skb_transport_header() with ipv6_hdr() + 1. - In vxlan_na_create(), replace first skb_transport_offset() with ipv6_hdr() + 1 and second with skb_network_offset() + sizeof(struct ipv6hdr). Additionally, ensure we pskb_may_pull() the whole skb as we need it to iterate over the options. Signed-off-by: Vincent Bernat <vincent@bernat.im> Signed-off-by: David S. Miller <davem@davemloft.net>

2017-04-03net: hns: Avoid Hip06 chip TX packet line buglipeng7-70/+169
There is a bug on Hip06 that tx ring interrupts packets count will be clear when drivers send data to tx ring, so that the tx packets count will never upgrade to packets line, and cause the interrupts engendered was delayed. Sometimes, it will cause sending performance lower than expected. To fix this bug, we set tx ring interrupts packets line to 1 forever, to avoid count clear. And set the gap time to 20us, to solve the problem that too many interrupts engendered when packets line is 1. This patch could advance the send performance on ARM from 6.6G to 9.37G when an iperf send thread on ARM and an iperf send thread on X86 for XGE.

2017-04-03net: hns: Fix to adjust buf_size of ring according to mtulipeng7-24/+337
Because buf_size of ring set to 2048, the process of rx_poll_one can reuse the page, therefore the performance of XGE can improve. But the chip only supports three bds in one package, so the max mtu is 6K when it sets to 2048. For better performane in litter mtu, we need change buf_size according to mtu. When user change mtu, hns is only change the desc in memory. There are some desc has been fetched by the chip, these desc can not be changed by the code. So it needs set the port loopback and send some packages to let the chip consumes the wrong desc and fetch new desc. Because the Pv660 do not support rss indirection, we need add version check in mtu change process.

Rather than just adding SGMII mode to the list, Florian suggests removing the list of interface modes entirely: It actually sounds like we should just kill the check entirely, it does not appear that any of the interface mode would not fundamentally be able to support EEE, because the "lowest" mode we support is MII, and even there it's quite possible to support EEE.

2017-04-01net: phy: avoid setting unsupported EEE advertismentsRussell King1-5/+10
We currently allow userspace to set any EEE advertisments it desires, whether or not the PHY supports them. For example: # ethtool --set-eee eth1 advertise 0xffffffff # ethtool --show-eee eth1 EEE Settings for eth1: EEE status: disabled Tx LPI: disabled Supported EEE link modes: 100baseT/Full 1000baseT/Full 10000baseT/Full Advertised EEE link modes: 100baseT/Full 1000baseT/Full 1000baseKX/Full 10000baseT/Full 10000baseKX4/Full 10000baseKR/Full Clearly, this is not sane, we should only allow link modes that are supported to be advertised (as we do elsewhere.) Ensure that we mask the MDIO_AN_EEE_ADV value with the capabilities retrieved from the MDIO_PCS_EEE_ABLE register.

2017-04-01net: dsa: Mock-up driverFlorian Fainelli5-1/+390
This patch adds support for a DSA mock-up driver which essentially does the following: - registers/unregisters 4 fixed PHYs to the slave network devices - uses eth0 (configurable) as the master netdev - registers the switch as a fixed MDIO device against the fixed MDIO bus at address 31 - includes dynamic debug prints for dsa_switch_ops functions that can be enabled to get call traces This is a good way to test modular builds as well as exercise the DSA APIs without requiring access to real hardware. This does not test the data-path, although this could be added later on. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-04-01net: dsa: mv88e6xxx: add cross-chip bridgingVivien Didelot1-1/+33
Implement the DSA cross-chip bridging operations by remapping the local ports an external source port can egress frames to, when this cross-chip port joins or leaves a bridge. The PVT is no longer configured with all ones allowing any external frame to egress any local port. Only DSA and CPU ports, as well as bridge group members, can egress frames on local ports.
