If the iucv_path_connect() call fails then return an error code that
corresponds to the iucv_path_connect() failure condition; instead of
returning -ECONNREFUSED for any failure.
This helps to improve error handling for user space applications
(e.g. inform the user that the z/VM guest is not authorized to
connect to other guest virtual machines).
The error return codes are based on those described in connect(2).

The flags field of struct ehea_port is only used with test_bit(),
clear_bit() and set_bit() and these interfaces only work on
"unsigned long"s, so change the field to be an "unsigned long". Also,
this field only has two bits defined for it (0 and 1) so will still be
fine if someone builds this driver for a 32 bit arch (at least as far as
this flags field is concerned).
Also note that ehea_driver_flags is only used in ehca_main.c, so make it
static in there.

Commit b47300168e770b60ab96c8924854c3b0eb4260eb "Do not fire linkwatch
events until the device is registered." was made as a workaround for
drivers that call netif_carrier_off before registering the device.
Unfortunately this causes these drivers to incorrectly report their
link status as IF_OPER_UNKNOWN which can falsely set the IFF_RUNNING
flag when the interface is first brought up. This issues was
previously pointed out[1] but was dismissed saying that IFF_RUNNING is
not related to the link status. From my digging IFF_RUNNING, as
reported to userspace, is based on the link state. It is set based on
__LINK_STATE_START and IF_OPER_UP or IF_OPER_UNKNOWN. See [2], [3],
and [4]. (Whether or not the kernel has IFF_RUNNING set in flags is
not reported to user space so it may well be independent of the link,
I don't know if and when it may get set.)
The end result depends slightly depending on the driver. The the two I
tested were e1000e and b44. With e1000e if the system is booted
without a network cable attached the interface will falsely report
RUNNING when it is brought up causing NetworkManager to attempt to
start it and eventually time out. With b44 when the system is booted
with a network cable attached and brought up with dhcpcd it will time
out the first time.
The attached patch that will still set the operstate variable
correctly to IF_OPER_UP/DOWN/etc when linkwatch_fire_event is called
but then return rather than skipping the linkwatch_fire_event call
entirely as the previous fix did. (sorry it isn't inline, I don't have
a patch friendly email client at the moment)

gro: Add page frag support
This patch allows GRO to merge page frags (skb_shinfo(skb)->frags)
in one skb, rather than using the less efficient frag_list.
It also adds a new interface, napi_gro_frags to allow drivers
to inject page frags directly into the stack without allocating
an skb. This is intended to be the GRO equivalent for LRO's
lro_receive_frags interface.
The existing GSO interface can already handle page frags with
or without an appended frag_list so nothing needs to be changed
there.
The merging itself is rather simple. We store any new frag entries
after the last existing entry, without checking whether the first
new entry can be merged with the last existing entry. Making this
check would actually be easy but since no existing driver can
produce contiguous frags anyway it would just be mental masturbation.
If the total number of entries would exceed the capacity of a
single skb, we simply resort to using frag_list as we do now.

ipv6: Fix sporadic sendmsg -EINVAL when sending to multicast groups.
Thanks to excellent diagnosis by Eduard Guzovsky.
The core problem is that on a network with lots of active
multicast traffic, the neighbour cache can fill up. If
we try to allocate a new route and thus neighbour cache
entry, the bog-standard GC attempt the neighbour layer does
in ineffective because route entries hold a reference
to the existing neighbour entries and GC can only liberate
entries with no references.
IPV4 already has a way to handle this, by doing a route cache
GC in such situations (when neigh attach returns -ENOBUFS).

m68k: mac baboon interrupt enable/disable
No-one seems to know how to mask individual baboon interrupts, so we just
mask the umbrella IRQ. This will work as long as only the IDE driver uses
the baboon chip (it can't deadlock). Use mac_enable_irq/mac_disable_irq
rather than enable_irq/disable_irq because the latter routines count the
depth of nested calls which triggers a warning and call trace because
IRQ_NUBUS_C is enabled twice in a row (once when the baboon handler is
registered, and once when the IDE IRQ is registered).

The initial skb may have been freed after napi_gro_complete in

we cannot check same_flow (which indicates whether it was merged)

This patch fixes this by saving the same_flow status before the

802.3ad has its own ethhdr-like structure in the form of an ad_header,

the same from the struct values, both are packed as well.
It's therefore perfectly fine to replace the ad_header by the ethhdr
and to remove its definition.
