* ipg: run-time configurable jumbo frame supportPekka Enberg2008-07-041-10/+32
| | | | | | | | | | Make jumbo frame support configurable via ifconfig mtu option as suggested by Stephen Hemminger.

| | | | | | | | | | Add a ->max_rxframe member to struct ipg_nic_private and convert the users of IPG_MAX_RXFRAME_SIZE to use it instead to enable per-device jumbo frame configuration.

* ipg: remove jumbo frame #ifdef from mtuPekka Enberg2008-07-041-3/+3
| | | | | | | | | Remove JUMBO_FRAME #ifdef from dev->mtu setting in ipg_nic_open() so that we can make IPG_TXFRAG_SIZE configurable. Tested-by: Andrew Savchenko <Bircoph@list.ru> Signed-off-by: Pekka Enberg <penberg@cs.helsinki.fi> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
* ipg: always compile in jumbo frame supportPekka Enberg2008-07-041-13/+14
| | | | | | | | | | | 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.

* ipg: use NULL, not zero, for pointersPekka Enberg2008-06-271-1/+1

* ipg: fix jumbo frame compilationPekka Enberg2008-06-271-7/+7
| | | | | | | | | Make jumbo frame support compile again. It was broken by the cleanup series before the merge because the code is hidden under JUMBO_FRAME #ifdef.

* ipg: fix Tx completion irq requestFrancois Romieu2008-01-171-4/+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>

* ipg: plug Tx completion leakFrancois Romieu2008-01-171-14/+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>
