To fix bugs when running offloaded FCoE/iSCSI traffic in multiple
Class of Service environments. In some scenarios, traffic could stop

On-stack initialization via assignment of flow structures are
expensive because GCC emits a memset() to clear the entire
structure out no matter what.Add a helper for ipv4 output flow key setup which we can use to avoid
the memset.Signed-off-by: David S. Miller

The IRQF_SAMPLE_RANDOM flag is marked as deprecated and will be removed.
Every input point to the kernel's entropy pool have to better document the
type of entropy source it is.drivers/char/random.c now implements a set of interfaces that can be used for
devices to collect enviromental noise. IRQF_SAMPLE_RANDOM will be replaced
with these add_*_randomness exported functions.Network drivers are not a good source of entropy. They use as a source of
entropy essentially a remote host. Which means that the source of entropy can
be potentially controlled by an attacker. Also, with heavy workloads the
entropy decreases due to less hardware interrupts happening thanks to irq
mitigation and NAPI.If a system relies in its network interface as a entropy source it has a false
sense of security. Systems that don't have devices whose drivers are good
sources of entropy, should either use a hardware random number generator or
feed the kernel's entropy pool from userspace using other sources of entropy
such as EGD, video_entropyd, timer_entropyd and audio-entropyd.Signed-off-by: Javier Martinez Canillas

Current enic code only supports ASSOCIATE and DISASSOCIATE port profile
operations. This patch adds enic support for port profile
PORT_REQUEST_PREASSOCIATE_RR operation. The VIC adapter (8021qbh) is capable
of handling port profile requests done in two steps namely PREASSOCIATE_RR
and ASSOCIATE today. The motivation to support PREASSOCIATE_RR comes mainly
from its use as an optimization during VM migration ie, to do resource
reservation on destination host before resources on source host are released.PREASSOCIATE_RR is a VDP operation and according to the latest at IEEE,
8021qbh will also need to support VDP commands.In addition to handling the new PORT_REQUEST_PREASSOCIATE_RR operation
this patch also does the below:
- Introduces handlers for PORT_REQUEST operations
- Moves most of the port profile handling code to new files enic_pp.[ch]
- Uses new fw devcmds for port profile operationsSigned-off-by: Roopa Prabhu

This patch introduces new fw devcmds for port profile handling.
These new commands are similar to the current fw commands for
port profile handling. The only difference being that the new
commands split the existing port profile handling devcmds into multiple
fw commands, giving the driver finer control over port profile operations.Signed-off-by: Roopa Prabhu

Commits 01a16b21 (netlink: kill eff_cap from struct netlink_skb_parms)
and c53fa1ed (netlink: kill loginuid/sessionid/sid members from struct
netlink_skb_parms) removed some members from struct netlink_skb_parms
that depend on the current context, all netlink users are now required
to do synchronous message processing.connector however queues received messages and processes them in a work
queue, which is not valid anymore. This patch converts connector to do
synchronous message processing by invoking the registered callback handler
directly from the netlink receive function.In order to avoid invoking the callback with connector locks held, a
reference count is added to struct cn_callback_entry, the reference
is taken when finding a matching callback entry on the device's queue_list
and released after the callback handler has been invoked.Signed-off-by: Patrick McHardy

Don't flap VCs when carrier state changes; higher-level protocols
can detect loss of connectivity and act accordingly. This is more
consistent with how other network interfaces work.We no longer use release_vccs() so we can delete it.
release_vccs() was duplicated from net/atm/common.c; make the
corresponding function exported, since other code duplicates it
and could leverage it if it were public.Signed-off-by: Philip A. Prindeville

Omit pkt_hdr preamble when dumping transmitted packet as hex-dump;
we can pull this up because the frame has already been sent, and

receive.Use "port" consistently instead of "device" intermittently.

- commit eead4d5c63ff ("powerpc: qe_ic: Rename get_irq_desc_data and
get_irq_desc_chip") made the helper functions use
irq_desc_get_handler_data() instead of the legacy (and no longer
existing) get_irq_desc_data.- commit d4db35e8dc96 ("powerpc/qe_ic: Fix another breakage from the
irq_data conversion") used irq_desc_get_chip_data() instead.According to Thomas, the former is the correct direct conversion, but it
does look like both should work (arch/powerpc/sysdev/qe_lib/qe_ic.c
seems to initialize both to the same thing), and the chip data in some
ways is the more logical. Somebody should really decide on one of the
other.This merge picks irq_desc_get_handler_data() as the straightforward pure
conversion to new names, as per Thomas.
