[8021Q]: transfer dev_id from real device

A net_device struct provides field dev_id. It is used for
unique ipv6 generation in case of shared network cards
(as for the OSA network cards of IBM System z).
If VLAN devices are built on top of such shared network cards,
this dev_id information needs to be transferred to the VLAN device.

    advertise the full capability when autoneg was set to on.

changed things around so that ethtool speed settings were strictly
followed.  Unfortunately ethtool doesn't seem to set ADVERTISED_Autoneg
in the advertising field (and maybe it shouldn't have to).  I'd vote
that it should be fixed there, but it should also be added here just in
case someone using ethtool ioctls in their own application gets what
they want.

[DCCP]: Twice the wrong reset code in receiving connection-Requests

This fixes two bugs in processing of connection-Requests in
v{4,6}_conn_request:

 1. Due to using the variable `reset_code', the Reset code generated
    internally by dccp_parse_options() is overwritten with the
    initialised value ("Too Busy") of reset_code, which is not what is
    intended.

 2. When receiving a connection-Request on a multicast or broadcast
    address, no Reset should be generated, to avoid storms of such
    packets. Instead of jumping to the `drop' label, the
    v{4,6}_conn_request functions now return 0. Below is why in my
    understanding this is correct:

    When the conn_request function returns < 0, then the caller,
    dccp_rcv_state_process(), returns 1. In all instances where
    dccp_rcv_state_process is called (dccp_v4_do_rcv, dccp_v6_do_rcv,
    and dccp_child_process), a return value of != 0 from
    dccp_rcv_state_process() means that a Reset is generated.

    If on the other hand the conn_request function returns 0, the
    packet is discarded and no Reset is generated.

Note: There may be a related problem when sending the Response, due to
the following.

if (dccp_v6_send_response(sk, req, NULL))
goto drop_and_free;
/* ... */
drop_and_free:
return -1;

In this case, if send_response fails due to transmission errors, the
next thing that is generated is a Reset with a code "Too Busy". I
haven't been able to conjure up such a condition, but it might be good
to change the behaviour here also (not done by this patch).

`-EMSGSIZE'.  In particular, as fragmentation is not currently
supported (and its use is partly discouraged in RFC 4340).

With this option, it is possible to size buffers accordingly, e.g.

/* or */

       unsigned int released, pending;

sp->txd_map is an u64
because :
dma_addr_t txd_map;

And in asm-i386/types.h, I see :
#ifdef CONFIG_HIGHMEM64G

#else
typedef u32 dma_addr_t;

I my config, I use CONFIG_HIGHMEM64G

sizeof(struct ipg_tx) is an u32

As detailed at https://bugs.gentoo.org/159646 hostap with hostapd confuses
udev by presenting 2 interfaces with the same MAC address. Also, at the time
of detection, the 'type' attribute is 1, identical to other hostap interfaces.

The AP interface is supposed to have type ARPHRD_IEEE80211 (801), but this is
not set until after registration.

Setting it before register_netdev() is called allows us to avoid this

to hostap_setup_dev().

[TCP]: Wrap-safed reordering detection FRTO check

In case somebody has a suggestion about a better place for this
check, which must guarantee execution "early enough" (i.e,
before the wrap can occur), I'm very open to them.

[TCP]: Update comment of SACK block validator

Just came across what RFC2018 states about generation of valid
SACK blocks in case of reneging. Alter comment a bit to point
out clearly.

IMHO, there isn't any reason to change code because the
validation is there for a purpose (counters will inform user
about decision TCP made if this case ever surfaces).

This was found due to bug report from Cedric Le Goater though
it turned this turned out to be unrelated bug.

[BNX2]: factor out gzip unpacker

This patch modifies gzip unpacking code in bnx2 driver so that
it does not depend on bnx2 internals. I will move this code
out of the driver and into zlib in follow-on patch.

It can be useful in other drivers which need to store firmwares
or any other relatively big binary blobs - fonts, cursor bitmaps,
whatever.

Patch is run tested by Michael Chan (driver author).

ax88796: add 93cx6 eeprom support

Hook up the 93cx6 eeprom code to the ax88796 driver and modify the ax88796
driver to read out the mac address from the eeprom.  We need this for the
ax88796 on certain SuperH boards.  The pin configuration used to connect
the eeprom to the ax88796 on these boards is the same as pointed out by the
ax88796 datasheet, so we can probably reuse this code for multiple
platforms in the future.

PHYLIB: fix an interrupt loop potential when halting

Ensure the PHY_HALTED state is not entered with the IRQ asserted as it
could lead to an interrupt loop.

There is a small window in phy_stop(), where the state of the PHY machine
indicates it has been halted, but its interrupt output might still be
unmasked.  If an interrupt goes active right at this moment it will loop as
the phy_interrupt() handler exits immediately with IRQ_NONE if the halted
state is seen.  It is unsafe to extend the phydev spinlock to cover
phy_interrupt().  It is safe to swap the order of the actions though as all
the competing places to unmask the interrupt output of the PHY, which are
phy_change() and phy_timer() are already covered with the lock as is the
sequence in question.
