Align the PCI Express #defines with the style used for the PCI-X 2012-09-18T22:04:59Z Gavin Atkinson gavin@FreeBSD.org 2012-09-18T22:04:59Z urn:sha1:389c8bd51ead1f1c111e8f8baad65762f6823ff4 #defines. This also has the advantage that it makes the names more compact, iand also allows us to correct the non-uniform naming of the PCIM_LINK_* defines, making them all consistent amongst themselves. This is a mostly mechanical rename: s/PCIR_EXPRESS_/PCIER_/g s/PCIM_EXP_/PCIEM_/g s/PCIM_LINK_/PCIEM_LINK_/g When this is MFC'd, #defines will be added for the old names to assist out-of-tree drivers. Discussed with: jhb MFC after: 1 week style. No functional changes. 2012-01-10T20:52:02Z Pyun YongHyeon yongari@FreeBSD.org 2012-01-10T20:52:02Z urn:sha1:0b6990445058a56f87cb1ab00cc206c9392a801b FreeBSD driver does not require arpcom structure in softc. 2011-12-09T23:37:55Z Pyun YongHyeon yongari@FreeBSD.org 2011-12-09T23:37:55Z urn:sha1:5effa1598aea80a8c0d10f759c647a704f55bf3b Announce flow control ability to PHY driver and enable RX flow 2011-12-09T19:10:38Z Pyun YongHyeon yongari@FreeBSD.org 2011-12-09T19:10:38Z urn:sha1:5d384a0de9e590036647cbf0e7db4f4404135657 control. Controller does not automatically generate pause frames based on number of available RX buffers so it's very hard to know when driver should generate XON frame in time. The only mechanism driver can detect low number of RX buffer condition is ET_INTR_RXRING0_LOW or ET_INTR_RXRING1_LOW interrupt. This interrupt is generated whenever controller notices the number of available RX buffers are lower than pre-programmed value( ET_RX_RING0_MINCNT and ET_RX_RING1_MINCNT register). This scheme does not provide a way to detect when controller sees enough number of RX buffers again such that efficient generation of XON/XOFF frame is not easy. While here, add more flow control related register definition. Remove unnecessary definition of ET_PCIR_BAR.

Note, interrupts are automatically ACKed when the status register is read. Add RX/TX DMA error to interrupt handler and do full controller reset if driver happen to encounter these errors. There is no way to recover from these DMA errors without controller reset. Rename local variable name intrs with status to enhance readability. While I'm here, rename ET_INTR_TXEOF and ET_INTR_RXEOF to ET_INTR_TXDMA and ET_INTR_RXDMA respectively. These interrupts indicate that a frame is successfully DMAed to controller's internal FIFO and they have nothing to do with EOF(end of frame). Driver does not need to wait actual end of TX/RX of a frame(e.g. no need to wait the end signal of TX which is generated when a frame in TX FIFO is emptied by MAC). Previous names were somewhat confusing. Disable all clocks and put PHY into COMA before entering into 2011-12-07T23:20:14Z Pyun YongHyeon yongari@FreeBSD.org 2011-12-07T23:20:14Z urn:sha1:38953bb0a52d4b9f8e04aca65148c19065bc0aea suspend state. This will save more power. On resume, make sure to enable all clocks. While I'm here, if controller is not fast ethernet, enable gigabit PHY.

Now, reinitializing is done only when driver is running. While here, remove unnecessary assignment of error value since it was already initialized to 0.
