zorro_device_id are not supposed to change at runtime. All functions working with zorro_device_id provided by <linux/zorro.h> work with const zorro_device_id. So mark the non-const structs as const. Signed-off-by:

Antoine Tenart says: ==================== net: mvpp2: MAC/GoP configuration This is based on net-next (e2a7c34f). I removed the GoP interrupt and PHY optional parts in this v2 to ease the review process as the MAC/GoP initialization seemed to start less discussions :) This series now only aims at making the PPv2 driver less depending on the firmware/bootloader initialization. Some patches cleanup some parts as well, and add new interface descriptions in the dt. The current implementation of the PPv2 driver relies on the firmware/bootloader initialization to configure some parts, as the Group of Ports (GoP) and the MACs (GMAC and/or XLG MAC --for 10G--). The drawback is the kernel must be configured to match exactly what the bootloader configures which is not convenient and is an issue when using boards having an Ethernet port and an SFP port wired to the same GoP port, as no dynamic configuration can be done. This series adds the GoP and GMAC/XLG MAC initializations so that the PPV2 does not have to rely on a previous initialization. One part is still missing from this series, and that would be the 'comphy' which provides shared serdes PHYs and which must be configured as well for a full kernel initialization to work. This comphy support will be part of a following up series. (This series was also tested with this 'comphy' support, as it's nearly ready). @Dave: patches 9 and 10 should go through the mvebu tree. Thanks! ==================== Signed-off-by:

The patch adds GoP (group of ports) initialization functions. The mvpp2 driver was relying on the firmware/bootloader initialization; this patch moves this setup to the mvpp2 driver. Signed-off-by:

This adds a routine to initialize the XLG MAC at the port level when using a port and the XAUI/10GKR interface mode. This wasn't done until this commit, and the mvpp2 driver was relying on the bootloader/firmware initialization. This doesn't mean everything is configured in the mvpp2 driver now, but it helps reducing the gap. Signed-off-by:

The patch adds ERSPAN type II tunnel support. The implementation is based on the draft at [1]. One of the purposes is for Linux box to be able to receive ERSPAN monitoring traffic sent from the Cisco switch, by creating a ERSPAN tunnel device. In addition, the patch also adds ERSPAN TX, so Linux virtual switch can redirect monitored traffic to the ERSPAN tunnel device. The traffic will be encapsulated into ERSPAN and sent out. The implementation reuses tunnel key as ERSPAN session ID, and field 'erspan' as ERSPAN Index fields: ./ip link add dev ers11 type erspan seq key 100 erspan 123 \ local 172.16.1.200 remote 172.16.1.100 To use the above device as ERSPAN receiver, configure Nexus 5000 switch as below: monitor session 100 type erspan-source erspan-id 123 vrf default destination ip 172.16.1.200 source interface Ethernet1/11 both source interface Ethernet1/12 both no shut monitor erspan origin ip-address 172.16.1.100 global [1] https://tools.ietf.org/html/draft-foschiano-erspan-01 [2] iproute2 patch: http://marc.info/?l=linux-netdev&m=150306086924951&w=2 [3] test script: http://marc.info/?l=linux-netdev&m=150231021807304&w=2Signed-off-by:

Remove two references to ufo in the udp send path that are no longer reachable now that ufo has been removed. Commit 85f1bd9a ("udp: consistently apply ufo or fragmentation") is a fix to ufo. It is safe to revert what remains of it. Also, no skb can enter ip_append_page with skb_is_gso true now that skb_shinfo(skb)->gso_type is no longer set in ip_append_page/_data. Signed-off-by:

Haiyang Zhang says: ==================== hv_netvsc: Ethtool handler to change UDP hash levels The patch set adds the functions to switch UDP hash level between L3 and L4 by ethtool command. UDP over IPv4 and v6 can be set differently. The default hash level is L4. We currently only allow switching TX hash level from within the guests. The ethtool callback function is triggered by command line, and update the per device variables of the hash level. On Azure, fragmented UDP packets is not yet supported with L4 hashing, and may have high packet loss rate. Using L3 hashing is recommended in this case. This ethtool option allows a user to make this selection. ==================== Signed-off-by: -

The Huawei's PCIE HiNIC card is a new Ethernet card and hence there was a need of a new driver. The current driver is meant to be used for the Physical Function and there would soon be a support for Virtual Function and more features once the basic PF driver has been accepted.
