David S. Miller 24743537d3 atm: iphase: Fix set-but-not-used warnings.
The "iavcc" and "iadev" cases are obvious.

The intr_status and frmr_intr cases are reading a register to clear
the chip status.  This driver is pretty old and creaky, and uses
volatile pointer dereferences to do register I/O when it should be
using readl() and friends.  However that it outside of the scope of
these changes.

Michał Mirosław 66371c4413 net: bnx2x: convert to hw_features
Since ndo_fix_features callback is postponing features change when
bp->recovery_state != BNX2X_RECOVERY_DONE, netdev_update_features()
has to be called again when this condition changes. Previously,
ethtool_ops->set_flags callback returned -EBUSY in that case
(it's not possible in the new model).

v5: - don't delay set_features, as it's rtnl_locked - same as recovery process
v4: - complete bp->rx_csum -> NETIF_F_RXCSUM conversion
    - add check for failed ndo_set_features in ndo_open callback

Jiri Pirko bcc6d47903 net: vlan: make non-hw-accel rx path similar to hw-accel
Now there are 2 paths for rx vlan frames. When rx-vlan-hw-accel is
enabled, skb is untagged by NIC, vlan_tci is set and the skb gets into
vlan code in __netif_receive_skb - vlan_hwaccel_do_receive.

For non-rx-vlan-hw-accel however, tagged skb goes thru whole
__netif_receive_skb, it's untagged in ptype_base hander and reinjected

This incosistency is fixed by this patch. Vlan untagging happens early in
__netif_receive_skb so the rest of code (ptype_all handlers, rx_handlers)
see the skb like it was untagged by hw.

David S. Miller d83d282bcb s2io: Fix warnings due to -Wunused-but-set-variable.
Most of these are cases where we are trying to read back a register
after a write to ensure completion.

Simply pre-fixing the readl() or readq() with "(void)" is sufficient
because these are volatile operations and the compiler cannot eliminate
them just because no real assignment takes place.

The case of free_rxd_blk()'s assignments to "struct buffAdd *ba" is a
real spurious assignment as this variable is completely otherwise
unused.

Ben Hutchings c44d79950b niu: Recognise original ethtool class code for AH/ESP flow hashing
When the RX network flow classification interface was originally
defined for reporting and controlling of flow hashing, AH and ESP were
not given distinct flow class codes (apparently because the Sun
Neptune hardware treats them very similarly).

For flow steering, they must be distinguished, so new and separate
flow class codes were added for AH and ESP.  But for backward-
compatibility, flow hash operations should continue to support the
original class codes.

converting the ethtool flow class code into a class code for Sun

really dealing with.  It may also return -1 (-EPERM) for some
unhandled ethtool flow class codes.

Alexander Duyck 127fe533ae v3 ethtool: add ntuple flow specifier data to network flow classifier
This change is meant to add an ntuple data extensions to the rx network flow
classification specifiers.  The idea is to allow ntuple to be displayed via
the network flow classification interface.

The first patch had some left over stuff from the original flow extension
flags I had added.  That bit is removed in this patch.

The second had some left over comments that stated we ignored bits in the
masks when we actually match them.

This work is based on input from Ben Hutchings.

This change is meant to prevent a possible null pointer dereference if
NETIF_F_NTUPLE is defined but the set_rx_ntuple function pointer is not.

The main motivation behind this patch is to eventually replace the ntuple
interfaces entirely with the network flow classifier interfaces.  This
allows the device drivers to maintain the ntuple check internally while
using the network flow classifier interface for setting up and displaying
rules.

This result in memory fragmentation and driver receives 18 frags for

Giuseppe CAVALLARO a08070acd4 stmmac: fix Transmit Underflow error
On some old MAC chips without COE sometime the
Transmit Underflow error is issued.

The driver aborted all the transmission process
and initialized it from scratch.
This breaks the network activity as raised by Nachiketa
on a SPEAr board.

The patch is to fix this rare underflow event.
The driver will only clear the interrupt and the Tx
DMA will go out the Suspend state as soon as the
descriptor is fetched again.
The driver will continue to bump-up the DMA FIFO threshold
that, indeed, helped somebody to prevent this kind of error
in the past as well.

Linus Torvalds b42282e5a0 pci: fix PCI bus allocation alignment handling
In commit 13583b1659 ("PCI: refactor io size calculation code") Ram
had a thinko in the refactorization of the code: the end result used the
variable 'align' for the bus alignment, but the original code used
'min_align'.

Since then, another use of that 'align' variable got introduced by
commit c8adf9a3e8 ("PCI: pre-allocate additional resources to devices
only after successful allocation of essential resources.")

Fix both of those uses to use 'min_align' as they should.

If the MAC features can be detected at probe time and not at open, then
stmmac_fix_features could be simplified by limiting hw_features. That's

never turned on.

Michał Mirosław 350fb32ae4 net: r8169: convert to hw_features
Simple conversion with a bit of needed cleanup.

This also fixes:
 - confusion around vlan_features in rtl8169_vlan_mode(),
 - problem with broken TSO for too big MTU (the limit is set
   at 0xFFF --- max MSS field value).

SG+IP_CSUM+TSO is left disabled by default, based on suggestion by
David Dillow.
