      [NET]: Add netlink connector. · 7672d0b5
      由 Evgeniy Polyakov 提交于 
      Kernel connector - new userspace <-> kernel space easy to use
communication module which implements easy to use bidirectional
message bus using netlink as it's backend.  Connector was created to
eliminate complex skb handling both in send and receive message bus
direction.

Connector driver adds possibility to connect various agents using as
one of it's backends netlink based network.  One must register
callback and identifier. When driver receives special netlink message
with appropriate identifier, appropriate callback will be called.

From the userspace point of view it's quite straightforward:

	socket();
	bind();
	send();
	recv();

But if kernelspace want to use full power of such connections, driver
writer must create special sockets, must know about struct sk_buff
handling...  Connector allows any kernelspace agents to use netlink
based networking for inter-process communication in a significantly
easier way:

int cn_add_callback(struct cb_id *id, char *name, void (*callback) (void *));
void cn_netlink_send(struct cn_msg *msg, u32 __groups, int gfp_mask);

struct cb_id
{
	__u32			idx;
	__u32			val;
};

idx and val are unique identifiers which must be registered in
connector.h for in-kernel usage.  void (*callback) (void *) - is a
callback function which will be called when message with above idx.val
will be received by connector core.

Using connector completely hides low-level transport layer from it's
users.

Connector uses new netlink ability to have many groups in one socket.

      [PATCH] Sun HME: enable and map PCI ROM properly · ce1289ad
      由 Willy Tarreau 提交于 
      This ports the Sun GEM ROM mapping/enable fixes it sunhme (which used
the same PCI ROM mapping code).

Without this, I get NULL MAC addresses for all 4 ports (it's a SUN QFE).
With it, I get the correct addresses (the ones printed on the label on
the card).

      Sun GEM ethernet: enable and map PCI ROM properly · 4120b028
      由 Linus Torvalds 提交于 
      This same patch was reported to fix the MAC address detection on sunhme
(next patch).  Most people seem to be running this on Sparcs or PPC
machines, where we get the MAC address from their respective firmware
rather than from the (previously broken) ROM mapping routines.

      hpt366: write the full 4 bytes of ROM address, not just low 1 byte · 9ec4ff42
      由 Linus Torvalds 提交于 
      This is one heck of a confused driver.  It uses a byte write to a dword
register to enable a ROM resource that it doesn't even seem to be using.
