A zero length frame filter was recently introduced in ROSE protocole.
Previous commit makes the same at AX25 protocole level.
This patch has the same purpose for NetRom protocole.
The reason is that empty frames have no meaning in NetRom protocole.Signed-off-by: Bernard Pidoux

commit 1577ecef766650a57fceb171acee2b13cbfaf1d3 ("netdev: Merge UCC
and gianfar MDIO bus drivers") broke the TSEC TBI PHY support: the
driver now refuses to probe TBI MDIO buses as it doesn't know about
"fsl,gianfar-tbi" compatible entry, and thus _probe() fails with
-ENODEV status.Fix this by adding "fsl,gianfar-tbi" to the list of known Gianfar
MDIO buses.Signed-off-by: Anton Vorontsov

This patch enables support for the new Intel 82552 adapter (new PHY paired
with the existing MAC in the ICH7 chipset). No new features are added to
the driver, however there are minor changes due to updated registers and a
few workarounds for hardware errata.Signed-off-by: Bruce Allan

dev_queue_xmit() needs to dirty fields "state", "q", "bstats" and "qstats"
On x86_64 arch, they currently span three cache lines, involving more
cache line ping pongs than necessary, making longer holding of queue spinlock.We can reduce this to one cache line, by grouping all read-mostly fields
at the beginning of structure. (Or should I say, all highly modified fields
at the end :) )Before patch :
offsetof(struct Qdisc, state)=0x38
offsetof(struct Qdisc, q)=0x48
offsetof(struct Qdisc, bstats)=0x80
offsetof(struct Qdisc, qstats)=0x90
sizeof(struct Qdisc)=0xc8After patch :

The watchdog will schedule an interrupt to help make sure queues are
cleaned in the case when an interrupt is missed, most likely due to very
high load. On 82599, there are extra interrupt registers to account for
the larger number of MSI-X vectors (64 total for 82599 vs. 18 total for
82598). These must be taken into account when performing this operation in
the watchdog.Signed-off-by: Jesse Brandeburg

As with igb, when the e1000e driver is fed 802.1q
packets with hardware checksum on, it chokes with an
error of the form:checksum_partial proto=81!
As the logic there was not smart enough to look into
the vlan header to pick out the encapsulated protocol.There are times when we'd like to send these packets
out without having to configure a vlan on the interface.
Here we check for the vlan tag and allow the packet to
go out wiht the correct hardware checksum.Thanks to Kand Ly for discovering the
issue and the coming up with a solution. This patch is
based upon his work.Fixups from Stephen Hemminger and

This patch replaces the generic eth_mac_addr function with one that
also updates the hardware mac address registers. It also renames the
existing smsc911x_set_mac_address function to
smsc911x_hw_set_mac_address for clarity.Newer LAN911x and all LAN921x devices also support changing the mac
address while the device is running, which is useful for some bonding
modes.Signed-off-by: Steve Glendinning

smsc911x_phy_adjust_link is called periodically by the phy layer (as
it's run in polling mode), and it only updates the hardware when it sees
a change in duplex or carrier. This patch clears the last known values
every time the interface is brought up, instead of only when the module
is loaded.Without this patch the adjust_link function never updates the hardware
after an ifconfig down; ifconfig up. On a full duplex link this causes
the tx error counter to increment, even though packets are correctly
transmitted, as the default MAC_CR register setting is for half duplex.The tx errors are "no carrier" errors, which should be ignored in
full-duplex mode. When MAC_CR is set to "full duplex" mode they are
correctly ignored by the hardware.Note that even with this patch the tx error counter can increment if
packets are transmitted between "ifconfig up" and the first phy poll
interval. An improved solution would use the phy interrupt with phylib,
but I haven't managed to make this work 100% robustly yet.Signed-off-by: Steve Glendinning

Tulip is currently doing request_irq before it has done its
initialization. This is usually not a problem because it hasn't
enable interrupts yet, but with DEBUG_SHIRQ on, we call the irq handler
when registering the interrupt as a sanity check.This can result in a NULL ptr dereference, so call tulip_init_ring
before request_irq, and add a free_ring function to do the freeing
now shared with tulip_close.Tested with a shell loop running ifup, ifdown in a loop a few hundred
times with DEBUG_SHIRQ on.Signed-off-by: Kyle McMartin

Impact: Make NetworkManager work with virtio_net
For now the semantics are simple: There is always carrier.
This allows a seamless experience with e.g., qemu/kvm
where NetworkManager just configures and sets up
everything automagically.If/when a generally agreed-upon way to control
carrier on/off in the emulator/hypervisor level
emerges, it will be trivial to extend the driver
to support that too, but for now even this 2-liner
makes user experience that much better.Signed-off-by: Pantelis Koukousoulas

The un-refactored code checked the link speed and duplex of
every slave on every pass; the refactored code did not do so.The 802.3ad and balance-alb/tlb modes utilize the speed and
duplex information, and require it to be kept up to date. This patch
adds a notifier check to perform the appropriate updating when the slave
device speed changes.Signed-off-by: Jay Vosburgh
