The interrupt status register for the natsemi chips is clear on read and was read unconditionally from both the interrupt and from the NAPI poll routine, meaning that if the interrupt service routine was called (for example, due to a shared interrupt) while a NAPI poll was scheduled interrupts could be missed. This patch fixes that by ensuring that the interrupt status register is only read by the interrupt handler when interrupts are enabled from the chip. It also reverts a workaround for this problem from the netpoll hook and improves the trace for interrupt events. Thanks to Sergei Shtylyov <sshtylyov@ru.mvista.com> for spotting the issue, Mark Huth <mhuth@mvista.com> for a simpler method and Simon Blake <simon@citylink.co.nz> for testing resources.

The natsemi drivers include functions for enabling and disabling interrupts from the chip but these are not used in all code paths. This patch changes the code paths that touch the interrupt enable register to use the functions. In all cases this adds an extra PCI read to post the operation but since none of these are in fast paths this shouldn't be too much of a problem. Signed-Off-By:

When bonding does fail over it calls set_mac_address. When this happens as the result of another port going down, the phy_mutex that is common to both ports is held, so it deadlocks. Setting the address doesn't need to do anything that needs the phy_mutex, it already has the RTNL to protect against other admin actions. This change just disables the receiver to avoid any hardware confusion while address is changing. Signed-off-by:

NB: driver is choke-full of code that will break on big-endian; as long as the hardware is onboard-only we can live with that, but sooner or later that'll need fixing. Signed-off-by:
