New revision of netxen chip has 2MB PCI memory. Older chips had 128MB addressable PCI memory. To retain compatibility, this patch adds function pointers based on pci bar0 size. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

o Reduce access to global arrays in data path. o Remove duplicate/unused variables, unecessary alignment constraints. o Use correct pci_dev instead of fallback device for consistent allocations. o Disable ethtool set_eeprom functionality for now, it was only used for flashing firmware.

o eliminate tx lock in netxen adapter struct, instead pound on netdev tx lock appropriately. o remove old "concurrent transmit" code that unnecessarily drops and reacquires tx lock in hard_xmit_frame(), this is already serialized the netdev xmit lock. o reduce scope of tx lock in tx cleanup. tx cleanup operates on different section of the ring than transmitting cpus and is guarded by producer and consumer indices. This fixes a race caused by rx softirq preemption on realtime kernels.

o separate and simpler irq handler for msi interrupts, avoids few checks than legacy mode. o avoid redudant tx_has_work() and rx_has_work() checks in interrupt and napi, which can uncork irq based on racy (lockless) access to tx and rx ring indices. If we get interrupt, there's sufficient reason to schedule napi. o replenish rx ring more often, remove self-imposed threshold rcv_free that prevents posting rx desc to card. This improves performance in low memory. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Tested-by: Vernon Mauery <mauery@us.ibm.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

Recent netxen firmware has new scheme of generating MSI interrupts, it raises interrupt and blocks itself, waiting for driver to unmask. This reduces chance of spurious interrupts. The driver will be able to deal with older firmware as well.

Here's the reworked patch. This cleans up some unnecessary byte-swapping while setting up tx and interpreting rx desc. The 64 bit rx status data should be converted to host endian format only once and the macros just need to extract bitfields. This saves a spate of interrupts on pseries blades caused by buggy (non) processing rx status ring. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

netxen driver allows limited number of threads simultaneously posting skb's in tx ring. If transmit slot is unavailable, driver calls schedule() or loops in xmit_frame(). This patch returns TX_BUSY and lets the stack reschedule the packet if transmit slot is unavailable. Also removes unnecessary check for tx timeout in the driver itself, the network stack does that anyway.

NetXen: Fix incorrect link status even with switch turned OFF. NetXen driver failed to accurately indicate when a link is up or down. This was encountered during failover testing, when the first port indicated that the link was up even when the 10G switch it was assigned to in the Bladecenter was turned off completely.
