ixgbe: Don't priority tag control frames in DCB mode

Certain types of control packets (LLDP, LACP, etc.) are not supposed to have a
priority tag or vlan tag inserted.  Ixgbe driver is currently priority
tagging everything (if packet is not on a VLAN interface).

This patch modifies DCB mode, so that packets marked with skb priority
TC_PRIO_CONTROL are not priority tagged.  It also transmits these packets on
the highest priority traffic class.
Programs (like dcbd) can set the skb priority using a socket option.  Or, a tc
filter can be configured to set the priority value. Using the value
TC_PRIO_CONTROL (7) has the benefit that it is already defined in the kernel,
and the bonding LACP code already sets the skb->priority field to this value.

register at91_ether using platform_driver_probe

at91ether_probe lives in .init.text, so using platform_driver_register
to register it is wrong because binding a device after the init memory
is discarded (e.g. via sysfs) results in an oops.

As requested by David Brownell platform_driver_probe is used instead of
moving the probe function to .devinit.text as proposed initially.
This saves some memory, but devices registered after the driver is
probed are not bound (probably there are none) and binding via sysfs
isn't possible.

fs_enet: Revive fixed link support

Since commit aa73832c5a80d6c52c69b18af858d88fa595dd3c ("Rework
fs_enet driver to use of_mdio infrastructure") the fixed-link support
is broken in the fs_enet driver.

This patch fixes the support by removing a check for phy_node, and adding
a call to of_phy_connect_fixed_link().

Also set netdev parent device via SET_NETDEV_DEV() call, this is needed
so that OF MDIO core could find a node pointer for a device.

Plus, fix "if (IS_ERR(phydev))" check, in case of errors,
of_phy_connect() returns NULL, not ERR_PTR as phy_connect().

of/mdio: Add support function for Ethernet fixed-link property

Fixed-link support is broken for the ucc_eth, gianfar, and fs_enet
device drivers.  The "OF MDIO rework" patches removed most of the
support. Instead of re-adding fixed-link stuff to the drivers, this
patch adds a support function for parsing the fixed-link property
and obtaining a dummy phy to match.

Note: the dummy phy handling in arch/powerpc is a bit of a hack and
needs to be reworked.  This function is being added now to solve the
regression in the Ethernet drivers, but it should be considered a
temporary measure until the fixed link handling can be reworked.

A pointer to mac_sonic_probe is passed to the core via

Various other functions that are called by mac_sonic_probe need to move

An alternative to this patch is using platform_driver_probe instead of

ath5k: temporarily disable crypto for AP mode

Pavel Roskin reported some issues with using AP mode without
nohwcrypt=1.  Most likely this is similar to the problem fixed
some time ago in ath9k by 3f53dd64f192450cb331c0fecfc26ca952fb242f,
"ath9k: Fix hw crypto configuration for TKIP in AP mode."

That only affects TKIP but it's easiest to just disable that and
WEP too until we get a proper fix in.

10 years agomac80211: disable mesh
Johannes Berg [Fri, 10 Jul 2009 09:38:14 +0000]
mac80211: disable mesh

My kvm instance was complaining a lot about sleeping
in atomic contexts in the mesh code, and it turns out
that both mesh_path_add() and mpp_path_add() need to
be able to sleep (they even use synchronize_rcu()!).
I put in a might_sleep() to annotate that, but I see
no way, at least right now, of actually making sure
those functions are only called from process context
since they are both called during TX and RX and the
mesh code itself even calls them with rcu_read_lock()
"held".

Therefore, let's disable it completely for now.

It's possible that I'm only seeing this because the
hwsim's beaconing is broken and thus the peers aren't
discovered right away, but it is possible that this
happens even if beaconing is working, for a peer that
doesn't exist or so.

It should be possible to solve this by deferring the
freeing of the tables to call_rcu() instead of using
synchronize_rcu(), and also using atomic allocations,
but maybe it makes more sense to rework the code to
not call these from atomic contexts and defer more of
the work to the workqueue. Right now, I can't work on
either of those solutions though.

The big differences between RDS 3.0 and 3.1 are protocol-level

always ends up in the header buffer, and the data goes in the data page.

In 3.0 our "header" is a trailer, and will end up either in the data
page, the header buffer, or split across the two. Since 3.1 is backwards-
