2008-01-17	ipg: fix Tx completion irq request	Francois Romieu	1	-4/+1
	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. Signed-off-by: Francois Romieu <romieu@fr.zoreil.com>

2008-01-17	ipg: plug Tx completion leak	Francois Romieu	1	-14/+5
	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. Signed-off-by: Francois Romieu <romieu@fr.zoreil.com>

2007-10-25	drivers/net/ipg.c: cleanups	Adrian Bunk	1	-1/+21
	This patch contains the following cleanups: - make ipg_nic_get_stats() static - move DefaultPhyParam[] from ipg.h to ipg.c and make it static Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-10-14	ipg: endianness fixes	Al Viro	1	-17/+17
	if your mask is host-endian, you should apply it after le64_to_cpu(); if it's little-endian - before. Doing both (for the same mask and little-endian value) is broken. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2007-10-10	ipg.c doesn't compile with with CONFIG_HIGHMEM64G	trem	1	-2/+8
	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.
