Instead, just drop these packets to match the behavior of other drivers. - Hold the driver lock in the interrupt handler to avoid races with ioctl requests to down the interface. Reviewed by: yongari

| | | | | | | | | | | | | | | | | | | | controller with Card Read Host Controller. These controllers are multi-function devices and have the same ethernet core of JMC250/JMC260. Starting from REVFM 5(chip full mask revision) controllers have the following features. o eFuse support o PCD(Packet Completion Deferring) o More advanced PHY power saving Because these controllers started to use eFuse, station address modified by driver is permanent as if it was written to EEPROM. If you have to change station address please save your controller default address to safe place before reprogramming it. There is no way to restore factory default station address. Many thanks to JMicron for continuing to support FreeBSD. HW donated by: JMicron

Experimentation shows retrying RX descriptor loading increased number of dropped frames under flow-control enabled environments so disable it and have controller generate RX empty interrupt as fast as it can. While I'm here fix RXCSR_DESC_RT_CNT macro.
* Convert the PHY drivers to honor the mii_flags passed down and convertmarius2010-10-151-17/+9
| | | | | | | | | | | | | | | | | | | | | | | the NIC drivers as well as the PHY drivers to take advantage of the mii_attach() introduced in r213878 to get rid of certain hacks. For the most part these were: - Artificially limiting miibus_{read,write}reg methods to certain PHY addresses; we now let mii_attach() only probe the PHY at the desired address(es) instead. - PHY drivers setting MIIF_* flags based on the NIC driver they hang off from, partly even based on grabbing and using the softc of the parent; we now pass these flags down from the NIC to the PHY drivers via mii_attach(). This got us rid of all such hacks except those of brgphy() in combination with bce(4) and bge(4), which is way beyond what can be expressed with simple flags. While at it, I took the opportunity to change the NIC drivers to pass up the error returned by mii_attach() (previously by mii_phy_probe()) and unify the error message used in this case where and as appropriate as mii_attach() actually can fail for a number of reasons, not just because of no PHY(s) being present at the expected address(es).

| | | | | | | | | | | | | | | | | | | | | | o Chip full mask revision 2 or later controllers have to set correct Tx MAC and Tx offload clock depending on negotiated link speed. o JMC260 chip full mask revision 2 has a silicon bug that can't handle 64bit DMA addressing. Add workaround to the bug by limiting DMA address space to be within 32bit. o Valid FIFO space of receive control and status register was changed on chip full mask revision 2 or later controllers. For these controllers, use default 16QW as it's supposed to be the safest value for maximum PCIe compatibility. JMicron confirmed performance will not be reduced even if the FIFO space is set to 16QW. o When interface is put into suspend/shutdown state, remove Tx MAC and Tx offload clock to save more power. We don't need Tx clock at all in this state. o Added new register definition for chip full mask revision 2 or later controllers. Thanks to JMicron for their continuous support of FreeBSD.

gigabit ethernet and JMC260 fast ethernet controllers. ATM jme(4) supports all hardware features except RSS and multiple Tx/Rx queue. In these days most ethernet controller vendors take a ply of concealing hardware detailes from open source developers. As contrasted with these vendors JMicron provided all necessary information needed to write a stable driver during driver writing and answered many questions I had. They even helped fixing driver bugs with protocol analyzer. Many thanks to JMicron for their support of FreeBSD. H/W donated by: JMicron
