* Increment if_ipackets in if_input().mpi2015-06-241-2/+1
| | | | | | | Note that pseudo-drivers not using if_input() are not affected by this conversion. ok mikeb@, kettenis@, claudio@, dlg@

| | | | | | | | | | | | there's no need to do it in m_devget(9). Stop passing an ``ifp'' will help for upcoming interface pointer -> index conversion. While here remove unused ``ifp'' argument from m_clget(9) and kill two birds^W layer violations in one commit. ok henning@

| | | | | | | | | | - Lower the max # of TX DMA segments from close to the whole ring down to a more sensible value. From FreeBSD - Move the TX ring full check out of and above the for loop. - Use dm_nsegs to provide the total # of DMA segments instead of the value from the for loop. ok mikeb@

Previously we were relying on specific DVACT_RESUME op's in drivers creating callback/threads themselves, but that has become too common, indicating the need for a built-in mechanism. ok dlg kettenis, tested by a sufficient amount of people

| | | | | | | | pci_set_powerstate() to using it instead. Many of these chunks of code had bugs in them, especially missing delay() calls. Some of them were doing things our PCI subsystem is now responsible for handling. If you have any of the affected devices, please keep an eye out for regressions. ok kettenis

* do not disable interrupts in the isr and then enable them againdlg2011-04-141-49/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | when leaving. when you're handling an interrupt it is masked. whacking the chip is work for no gain. modify the interrupt handler so it only processes the rings once, rather than looping over them until it runs out of work to do. looping in the isr is bad for several reasons: firstly, the chip does interrupt mitigation so you have a decent/predictable amount of work to do in the isr. your first loop will do that chunk of work (ie, it pulls off 50ish packets), and then the successive looping aggressively pull one or two packets off the rx ring. these extra loops work against the benefit that interrupt mitigation provides. bus space reads are slow. we should avoid doing them where possible (but we should always do them when necessary). doing the loop 5 times per isr works against the mclgeti semantics. it knows a nic is busy and therefore needs more rx descriptors by watching to see when the nic uses all of its descriptors between interrupts. if we're aggressively pulling packets off by looping in the isr then we're skewing this check. ok henning@ krw@ testing by sthen@

* First step towards cleaning up the Ethernet driver ioctl handling.brad2008-10-021-9/+2
| | | | | | | | | | | | | | | | | | | | Move calling ether_ioctl() from the top of the ioctl function, which at the moment does absolutely nothing, to the default switch case. Thus allowing drivers to define their own ioctl handlers and then falling back on ether_ioctl(). The only functional change this results in at the moment is having all Ethernet drivers returning the proper errno of ENOTTY instead of EINVAL/ENXIO when encountering unknown ioctl's. Shrinks the i386 kernels by.. RAMDISK - 1024 bytes RAMDISKB - 1120 bytes RAMDISKC - 832 bytes Tested by martin@/jsing@/todd@/brad@ Build tested on almost all archs by todd@/brad@ ok jsing@
