vlan: Add features for stacked vlan device

2015-03-29T20:33:21+00:00

Stacked vlan devices curretly have few features (GRO, HIGHDMA, LLTX). Since we have software fallbacks in case the NIC can not handle some features for multiple vlans, we can add the same features as the lower vlan devices for stacked vlan devices. This allows stacked vlan devices to create large (GSO) packets and not to segment packets. Those packets will be segmented by software on the real device, or even can be segmented by the NIC once TSO for multiple vlans becomes enabled by the following patches. The exception is those related to FCoE, which does not have a software fallback. Signed-off-by: Toshiaki Makita Signed-off-by: David S. Miller

8021q: Use eth__addr instead of memset

Use the built-in function instead of memset. Signed-off-by: Joe Perches Signed-off-by: David S. Miller

net: Kill dev_rebuild_header

2015-03-02T21:43:41+00:00

Now that there are no more users kill dev_rebuild_header and all of it's implementations. This is long overdue. Signed-off-by: "Eric W. Biederman" Signed-off-by: David S. Miller

vlan: Add ability to always enable TSO/UFO

2014-12-12T15:58:53+00:00

Since the real device can segment packets by software, a vlan device can set TSO/UFO even when the real device doesn't have those features. Unlike GSO, this allows packets to be segmented after Qdisc. Signed-off-by: Toshiaki Makita Signed-off-by: David S. Miller

vlan: Pass ethtool get_ts_info queries to real device.

2014-11-21T20:35:53+00:00

Commit a6111d3c "vlan: Pass SIOC[SG]HWTSTAMP ioctls to real device" intended to enable hardware time stamping on VLAN interfaces, but passing SIOCSHWTSTAMP is only half of the story. This patch adds the second half, by letting user space find out the time stamping capabilities of the device backing a VLAN interface. Signed-off-by: Richard Cochran Signed-off-by: David S. Miller

vlan: make __vlan_hwaccel_put_tag return void

Always returns the same skb it gets, so change to void. Signed-off-by: Jiri Pirko Acked-by: Pravin B Shelar Signed-off-by: David S. Miller

net: better IFF_XMIT_DST_RELEASE support

2014-10-07T17:22:11+00:00

Testing xmit_more support with netperf and connected UDP sockets, I found strange dst refcount false sharing. Current handling of IFF_XMIT_DST_RELEASE is not optimal. Dropping dst in validate_xmit_skb() is certainly too late in case packet was queued by cpu X but dequeued by cpu Y The logical point to take care of drop/force is in __dev_queue_xmit() before even taking qdisc lock. As Julian Anastasov pointed out, need for skb_dst() might come from some packet schedulers or classifiers. This patch adds new helper to cleanly express needs of various drivers or qdiscs/classifiers. Drivers that need skb_dst() in their ndo_start_xmit() should call following helper in their setup instead of the prior : dev->priv_flags &= ~IFF_XMIT_DST_RELEASE; -> netif_keep_dst(dev); Instead of using a single bit, we use two bits, one being eventually rebuilt in bonding/team drivers. The other one, is permanent and blocks IFF_XMIT_DST_RELEASE being rebuilt in bonding/team. Eventually, we could add something smarter later.

vlan: Pass SIOC[SG]HWTSTAMP ioctls to real device

2014-07-07T23:57:26+00:00

This allows applications to enable hardware timestamping without being aware of it being a vlan device and figuring out the real device. Signed-off-by: Stefan Sørensen Signed-off-by: David S. Miller
