Josh Boyer 84aee4889e ibm_emac: Remove the ibm_emac driver
The arch/ppc sub-tree has been removed in the powerpc git tree.  The old
ibm_emac driver is no longer used by anything as a result of this.  This
removes it, leaving the ibm_newemac driver as the proper driver to use for
PowerPC boards with the EMAC hardware.

Radu Cristescu 58c7821c42 atl1: relax eeprom mac address error check
The atl1 driver tries to determine the MAC address thusly:

	- If an EEPROM exists, read the MAC address from EEPROM and
	  validate it.
	- If an EEPROM doesn't exist, try to read a MAC address from
	  SPI flash.
	- If that fails, try to read a MAC address directly from the
	  MAC Station Address register.
	- If that fails, assign a random MAC address provided by the
	  kernel.

We now have a report of a system fitted with an EEPROM containing all
zeros where we expect the MAC address to be, and we currently handle
this as an error condition.  Turns out, on this system the BIOS writes
a valid MAC address to the NIC's MAC Station Address register, but we
never try to read it because we return an error when we find the all-
zeros address in EEPROM.

This patch relaxes the error check and continues looking for a MAC
address even if it finds an illegal one in EEPROM.

David Brownell 7dac6f8df6 net/enc28j60: low power mode
Keep enc28j60 chips in low-power mode when they're not in use.
At typically 120 mA, these chips run hot even when idle; this
low power mode cuts that power usage by a factor of around 100.

This version provides a generic routine to poll a register until
its masked value equals some value ... e.g. bit set or cleared.
It's basically what the previous wait_phy_ready() did, but this
version is generalized to support the handshaking needed to
enter and exit low power mode.

Bernard Pidoux fe2c802ab6 rose: improving AX25 routing frames via ROSE network
ROSE network is organized through nodes connected via hamradio or Internet.
AX25 packet radio frames sent to a remote ROSE address destination are routed
through these nodes.

Without the present patch, automatic routing mechanism did not work optimally
due to an improper parameter checking.

rose_get_neigh() function is called either by rose_connect() or by
rose_route_frame().

In the case of a call from rose_connect(), f0 timer is checked to find if a connection
is already pending. In that case it returns the address of the neighbour, or returns a NULL otherwise.

When called by rose_route_frame() the purpose was to route a packet AX25 frame
through an adjacent node given a destination rose address.
However, in that case, t0 timer checked does not indicate if the adjacent node
is actually connected even if the timer is not null. Thus, for each frame sent, the
function often tried to start a new connexion even if the adjacent node was already connected.

The patch adds a "new" parameter that is true when the function is called by
rose route_frame().
This instructs rose_get_neigh() to check node parameter "restarted". 
If restarted is true it means that the route to the destination address is opened via a neighbour
node already connected.
If "restarted" is false the function returns a NULL.
In that case the calling function will initiate a new connection as before.

This results in a fast routing of frames, from nodes to nodes, until
destination is reached, as originaly specified by ROSE protocole.

Steffen Klassert fe833fca2e xfrm: fix fragmentation for ipv4 xfrm tunnel
When generating the ip header for the transformed packet we just copy
the frag_off field of the ip header from the original packet to the ip
header of the new generated packet. If we receive a packet as a chain
of fragments, all but the last of the new generated packets have the
IP_MF flag set. We have to mask the frag_off field to only keep the
IP_DF flag from the original packet. This got lost with git commit

One way to fix this would be to split helper cleanup from the unregistration
function and invoke it for the H.245 helper, but since ctnetlink needs to be
able to find the helper for synchonization purposes, a better fix is to
register it normally and make sure its not assigned to connections during
helper lookup. The missing l3num initialization is enough for this, this
patch changes it to use AF_UNSPEC to make it more explicit though.

David S. Miller 9375cb8a12 ax25: Use sock_graft() and remove bogus sk_socket and sk_sleep init.
The way that listening sockets work in ax25 is that the packet input
code path creates new socks via ax25_make_new() and attaches them
to the incoming SKB.  This SKB gets queued up into the listening
socket's receive queue.

When accept()'d the sock gets hooked up to the real parent socket.
Alternatively, if the listening socket is closed and released, any
unborn socks stuff up in the receive queue get released.

So during this time period these sockets are unreachable in any
other way, so no wakeup events nor references to their ->sk_socket
and ->sk_sleep members can occur.  And even if they do, all such
paths have to make NULL checks.

So do not deceptively initialize them in ax25_make_new() to the
values in the listening socket.  Leave them at NULL.

Finally, use sock_graft() in ax25_accept().
