This reverts commit d7559982701ac500662b2e8e150ff34f7faf0281.
It wasn't meant to be applied, commit
342b7b741d76bc8aadeff844634348bb2a343d19 ("net: ti cpsw ethernet: set
IFCTL_A bit in MACCONTROL") was redone in such a way to make this
commit unnecessary.Signed-off-by: David S. Miller

Due to a bug in most Flexcan cores, the bus error interrupt needs
to be enabled. Otherwise we don't get any error warning or passive
interrupts. This is _not_ necessary for the i.MX28 and this patch
disables bus error interrupts if "berr-reporting" is not requested.
This avoids bus error flooding, which might harm, especially on
low-end systems.To handle such quirks of the Flexcan cores, a hardware feature flag
has been introduced, also replacing the "hw_ver" variable. So far
nobody could tell what Flexcan core version is available on what
Freescale SOC, apart from the i.MX6Q and P1010, and which bugs or
features are present on the various "hw_rev".CC: Hui Wang

Add the rtnl_link_ops changelink and fill_info callbacks, through
which the admin can now set/get the driver mode, etc policies.
Maintain the proprietary sysfs entries only for legacy childs.For child devices, set dev->iflink to point to the parent
device ifindex, such that user space tools can now correctly
show the uplink relation as done for vlan, macvlan, etc

Allow users to specify the phy interface of the CPSW slaves. The new

For RMII/RGMII mode operation in 100Mbps, the CPSW needs to set the
IFCTL_A bits in the MACCONTROL register. For all other PHY modes, this
bit is unused, so setting it unconditionally shouldn't cause any
trouble.Signed-off-by: Daniel Mack

After commit e22979d96a55d (mlx4_en: Moving to Interrupts for TX
completions) we no longer need to orphan skbs in mlx4_en_xmit()
since skb wont stay a long time in TX ring before their release.Orphaning skbs in ndo_start_xmit() should be avoided as much as
possible, since it breaks TCP Small Queue or other flow control
mechanisms (per socket limits)Signed-off-by: Eric Dumazet

Add GRO capability to IPv4 GRE tunnels, using the gro_cells
infrastructure.Tested using IPv4 and IPv6 TCP traffic inside this tunnel, and
checking GRO is building large packets.Signed-off-by: Eric Dumazet
Signed-off-by: David S. Miller -
This adds a new include file (include/net/gro_cells.h), to bring GRO
(Generic Receive Offload) capability to tunnels, in a modular way.Because tunnels receive path is lockless, and GRO adds a serialization
using a napi_struct, I chose to add an array of up to
DEFAULT_MAX_NUM_RSS_QUEUES cells, so that multi queue devices wont be
slowed down because of GRO layer.skb_get_rx_queue() is used as selector.
In the future, we might add optional fanout capabilities, using rxhash
for example.With help from Ben Hutchings who reminded me
netif_get_num_default_rss_queues() function.Signed-off-by: Eric Dumazet

skb with CHECKSUM_NONE cant currently be handled by GRO, and

When an address is added on loopback (ip -6 a a 2002::1/128 dev lo), two routes
are added:
- one in the local table:
local 2002::1 via :: dev lo proto none metric 0
- one the in main table (for the prefix):
unreachable 2002::1 dev lo proto kernel metric 256 error -101When the address is deleted, the route inserted in the main table remains
because we use rt6_lookup(), which returns NULL when dst->error is set, which
is the case here! Thus, it is better to use ip6_route_lookup() to avoid this
kind of filter.Signed-off-by: Nicolas Dichtel

This patch moves the bnx2x and cnic drivers into using FW 7.8.2
which was recently submitted into the linux-firmware tree.A short summary of minor bugs fixed by this FW:
1. In switch dependent mode, fix several issues regarding inner vlan
vs. DCB priorities.
2. iSCSI - not all packets were completed on a forward channel.
3. DCB - fixed for 4-port devices.
4. Fixed false parity reported in CAM memories when operating near -5%
on the 1.0V core supply.
5. ETS default settings are set to fairness between traffic classes
(rather than strict priority), and uses the same chip receive buffer
configuration for both PFC and pause.For a complete list of fixes made by this FW, see commit 236367db
in the linux-firmware git repository.Signed-off-by: Yuval Mintz

1) link_status_query() is always called to query the link-speed (speed
after applying qos). When there is no qos setting, link-speed is derived from
port-speed. Do all this inside this routine and hide this from the callers.2) adpater->phy.forced_port_speed is not being set anywhere after being
initialized. Get rid of this variable.3) Ignore async link_speed notifications till the initial value has been
fetched from FW.Signed-off-by: Sathya Perla

Simple round-robin hardware TX scheduling can cause starvation of TX rings
with small packets when other TX rings have large TSO or jumbo packets.In the simplest case, consider 2 TCP streams running in opposite
directions. The TSO TX traffic will hash to one ring and the ACKs for the
incoming data on a different TCP connection will hash to a different TX
ring. The hardware fetches one complete TSO packet (up to 64K data)
before servicing the other TX ring. When it gets to the other TX ring, it
will only fetch one packet (64-byte ACK packet in this case). After that,
it will switch back to the 1st ring filled with more TSO packets. Because
only one ACK can go out roughly every 500 usec in this case, the incoming
data rate becomes very low.Update version to 3.125.
