The generic packet receive code takes care of setting
netdev->last_rx when necessary, for the sake of the
bonding ARP monitor.
Drivers need not do it any more.
Some cases had to be skipped over because the drivers
were making use of the ->last_rx value themselves.

Add a ->is_jumbo boolean to struct ipg_nic_private and fix up
ipg_interrupt_handler() to call the jumbo frame version of ipg_nic_rx() if the
boolean is set to true. Also remove the JUMBO_FRAME #ifdefs so we can always
compile in support for jumbo frames.

The current logic will only request an ack for the first pending
packet. No irq is triggered as soon as the CPU submits a few
packets a bit quickly. Let's request an irq for every packet
instead.

The Tx skb release could not free more than one skb per call.
Add it to the fact that the xmit handler does not check for
a queue full condition and you have a recipe to leak quickly.
Let's release every pending Tx descriptor which has been given
back to the host CPU by the network controller. The xmit handler
suggests that it is done through the IPG_TFC_TFDDONE bit.
Remove the former "curr" computing: it does not produce anything
usable in its current form.

if it's little-endian - before. Doing both (for the same mask and

I've tried to compile 2.6.23-rc8-mm2, but it fails on ipg.c with the
error : ERROR: "__udivdi3" [drivers/net/ipg.ko] undefined!
I've instigated a bit, and I've found this code in ipg.c :
static void ipg_nic_txfree(struct net_device *dev)
{
struct ipg_nic_private *sp = netdev_priv(dev);
void __iomem *ioaddr = sp->ioaddr;
const unsigned int curr = ipg_r32(TFD_LIST_PTR_0) -
(sp->txd_map / sizeof(struct ipg_tx)) - 1;
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
typedef u64 dma_addr_t;
#else
typedef u32 dma_addr_t;
#endif
I my config, I use CONFIG_HIGHMEM64G
sizeof(struct ipg_tx) is an u32
So the div failed on i386 because of u64 / u32.
