net: rtnetlink - make create_link take name_assign_type

2014-07-15T23:13:07+00:00

This passes down NET_NAME_USER (or NET_NAME_ENUM) to alloc_netdev(),
for any device created over rtnetlink.

veth: add netpoll support

2014-06-25T23:35:37+00:00

It is trivial to add netpoll support to veth, since
it is not a stacked device, we don't need to setup and
clean up netpoll.

Conflicts:
	drivers/net/ethernet/marvell/mvneta.c

The mvneta.c conflict is a case of overlapping changes,
a conversion to devm_ioremap_resource() vs. a conversion
to netdev_alloc_pcpu_stats.

veth: Turn off vlan rx acceleration in vlan_features

2014-03-28T21:16:51+00:00

For completeness, turn off vlan rx acceleration in vlan_features so
that it doesn't show up on q-in-q setups.

net: Replace u64_stats_fetch_begin_bh to u64_stats_fetch_begin_irq

2014-03-15T02:41:36+00:00

Replace the bh safe variant with the hard irq safe variant.

We need a hard irq safe variant to deal with netpoll transmitting
packets from hard irq context, and we need it in most if not all of
the places using the bh safe variant.

Except on 32bit uni-processor the code is exactly the same so don't
bother with a bh variant, just have a hard irq safe variant that
everyone can use.

Conflicts:
	drivers/net/wireless/ath/ath9k/recv.c
	drivers/net/wireless/mwifiex/pcie.c
	net/ipv6/sit.c

The SIT driver conflict consists of a bug fix being done by hand
in 'net' (missing u64_stats_init()) whilst in 'net-next' a helper
was created (netdev_alloc_pcpu_stats()) which takes care of this.

The two wireless conflicts were overlapping changes.

veth: Fix vlan_features so as to be able to use stacked vlan interfaces

2014-02-20T07:15:38+00:00

Even if we create a stacked vlan interface such as veth0.10.20, it sends
single tagged frames (tagged with only vid 10).
Because vlan_features of a veth interface has the
NETIF_F_HW_VLAN_[CTAG/STAG]_TX bits, veth0.10 also has that feature, so
dev_hard_start_xmit(veth0.10) doesn't call __vlan_put_tag() and
vlan_dev_hard_start_xmit(veth0.10) overwrites vlan_tci.
This prevents us from using a combination of 802.1ad and 802.1Q
in containers, etc.

rtnl: make ifla_policy static

The only place this is used outside rtnetlink.c is veth. So provide
wrapper function for this usage.

net: introduce netdev_alloc_pcpu_stats() for drivers

2014-02-14T20:49:55+00:00

There are many drivers calling alloc_percpu() to allocate pcpu stats
and then initializing ->syncp. So just introduce a helper function for them.
