The VIA driver has changed the default for the DMA_LENGTH_DEF parameter.

This patch adds NAPI support for VIA velocity. The new velocity_poll
function also pairs tx/rx handling twice which improves perforamance on
some workloads (e.g., netperf UDP_STREAM) significantly (that part is
from the VIA driver).

(Partially from the upstream VIA driver). Tweaking the number of

(From the VIA driver). The current code does not guarantee 64-byte
alignment since it simply does

        int add = skb->data & 63;

        skb->data += add;

(via skb_reserve). So for example, if the skb->data address would be
0x10, this would result in 32-byte alignment (0x10 + 0x10).

Correct by adding

        64 - (skb->data & 63)

instead.

Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Adding a xfrm_state requires an authentication algorithm specified
either as xfrm_algo or as xfrm_algo_auth with a specific truncation
length. For compatibility, both attributes are dumped to userspace,
and we also accept both attributes, but prefer the new syntax.

If no truncation length is specified, or the authentication algorithm
is specified using xfrm_algo, the truncation length from the algorithm
description in the kernel is used.

The new XFRMA_ALG_AUTH_TRUNC attribute taking a xfrm_algo_auth as

currently blink the others in a timer function.  Since all PHYs have
simple on and off modes, we don't gain anything by using multiple

is no need to use a timer.

current tx/rx byte counts and priv->led_tpt.

priv->led_tpt should not get reset in iwl_leds_init(), this function can be
called by bring interface "up" or "down", or when uCode sysassert occurred.
resetting the led_tpt parameter will introduce incorrect led blinking behavior.
