2009-10-15Add detach support to a few more drivers, and in others do the neccessaryTheo de Raadt
operations in the detach function in the right order. Also ensure that the interrupt handlers not trust registers that go away. read over very carefully by dms, tested by me
2009-08-10More cases of shutdown hooks not needed after card is already stopped. InTheo de Raadt
these cases the xxstop function is a bit more complicated and has a flag of some sort, but the use of that flag does not matter; DMA is already ceased ok dlg
2009-08-09MCLGETI() will now allocate a mbuf header if it is not provided, thusTheo de Raadt
reducing the amount of splnet/splx dancing required.. especially in the worst case (of m_cldrop) ok dlg kettenis damien

2009-01-27make drivers tell the mclgeti allocator what their maximum ring size isDavid Gwynne
to prevent the hwm growing beyond that. this allows the livelock mitigation to do something where the hwm used to grow beyond twice the rx rings size. ok kettenis@ claudio@

2008-11-07Simplify the interface flag handling in the ioctl handler.Brad Smith
2008-11-07Remove storing the Ethernet header in the receve interrupt handler, theBrad Smith
disabled code that used to use this was removed 7 years ago.
2008-11-07- According to the Apple GMAC driver, the GEM ASIC specification andBrad Smith
the OpenSolaris eri(7D) the TX FIFO threshold has to be set to 0x4ff for the Gigabit variants and 0x100 for the ERI in order to avoid TX underruns. - Turn on workarounds for silicon bugs in the Apple GMAC variants. This was based on information obtained from the Darwin GMAC and Linux GEM drivers. - Turn on "infinite" (i.e. maximum 31 * 64 bytes in length) DMA bursts. From FreeBSD Tested by a few users with Apple GMAC's and Sun ERI.
2008-10-02First step towards cleaning up the Ethernet driver ioctl handling.Brad Smith
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@

Really just the low-hanging fruit of (hopefully) forthcoming timeout conversions. ok art@, krw@
2008-08-30Fix an issue initially reported by drahn@ with gem(4) where theseBrad Smith
drivers can report 2-3x times the number of actual packets being transmitted by only incrementing the counter for descriptors with buffers being freed. ok kettenis@
2008-08-26Fix a couple of problems that may make gem(4) get stuck:Mark Kettenis
1. If bus_dmamap_load_mbuf() fails because there are not enough segments in the map, defrag the mbuf. 2. If there are not enough free (hardware ring) descriptors, set IFF_OACTIVE and keep the packet on the queue. 3. If there is some other resource starvation that makes bus_dmamap_load_mbuf() or defragmentation fail, drop the packet. Don't set IFF_OACTIVE, since the Tx ring could be empty and we'd be stuck. 4. Only pass packets that are actually handed off to the hardware to BPF. Do so before handing them off to the hardware to make sure the packet isn't freed behind our back. ok dlg@
2008-05-31Properly set the IFF_OACTIVE flag if all the descriptrs are in use forBrad Smith
the TX ring and clear the flag when some have been freed. ok dlg@ kettenis@
