This commit was manufactured to restore the state of the 6.3-RELEASE image. 2007-09-15T10:56:00Z Marius Strobl marius@FreeBSD.org 2007-09-15T10:56:00Z urn:sha1:67f8112611524876d540c7dedd14a9507a940ff7 lance.c 1.3, 1.4; lancevar.h 1.3 - Use our own callout instead of if_slowtimo() for driving lance_watchdog() in order to avoid races accessing if_timer. - Use bus_get_dma_tag() to obtain the parent DMA tag so le(4) works on platforms requiring this. - Remove BUS_DMA_WAITOK from bus_dma_tag_create() invocations as it's no valid flag there. - For setting the port PCnet chips must be powered down or stopped and unlike documented may not take effect without an initialization. So don't invoke (*sc_mediachange) directly in lance_mediachange() but go through lance_init_locked(). It's suboptimal to impose this for all chips but given that besides the affected PCI bus front-end the only other front-end which supports media selection is and likely ever will be the 'ledma' front-end I see not enough reason to break the in-driver API for this (though one could argue both ways here). 2006-06-18T15:43:18Z Marius Strobl marius@FreeBSD.org 2006-06-18T15:43:18Z urn:sha1:79bf574325c6dadb063f9f127770a3d6be8b6498 lance.c 1.2, lancereg.h 1.2, lancevar.h 1.2 - Rearrange the code related to RX interrupt handling so that ownership of RX descriptors is immediately returned to the NIC after we have copied the data of the hardware, allowing the NIC to already reuse the descriptor while we are processing the data in ifp->if_input(). This results in a small but measurable increase in RX throughput. As a side-effect, this moves the workaround for the LANCE revision C bug to am7900.c (still off by default as I doubt we will actually encounter such an old chip in a machine running FreeBSD) and the workaround for the bug in the VMware PCnet-PCI emulation to am79000.c, which is now also only compiled on i386 (resulting in a small increase in RX throughput on the other platforms). - Change the RX interrupt handlers so that the descriptor error bits are only check once in case there was no error instead of twice (inspired by the NetBSD pcn(4), which additionally predicts the error branch as false). - Fix the debugging output of the RX and TX interrupt handlers; while looping through the descriptors print info about the currently processed one instead of always the previously last used one; remove pointless printing of info about the RX descriptor bits after their values were reset. - Create the DMA tags used to allocate the memory for the init block, descriptors and packet buffers with the alignment the respective NIC actually requires rather than using PAGE_SIZE unconditionally. This might as well fix the alignment of the memory as it seems we do not inherit the alignment constraint from the parent DMA tag. - For the PCI variants double the number of RX descriptors and buffers from 8 to 16 as this minimizes the number of RX overflows im seeing with one NIC-mainboard combination. Nevertheless move reporting of overflows under debugging as they seem unavoidable with some crappy hardware. - Add a comment regarding usage of ILACC vs. PCnet-PCI mode. - Fix the driver name part in the MODULE_DEPEND of the PCI front-end for ether. - Use different device descriptions for PCnet-Home and PCnet-PCI. - Fix some 0/NULL confusion in lance_get(). - Use bus_addr_t for sc_addr and bus_size_t for sc_memsize as these are more appropriate than u_long for these. - Remove the unused LE_DRIVER_NAME macro. - Add a comment describing why we are taking the LE_HTOLE* etc approach instead of using byteorder(9) functions directly. - Improve some comments and fix some wording. 2006-03-25T12:13:21Z Marius Strobl marius@FreeBSD.org 2006-03-25T12:13:21Z urn:sha1:4677688976c1c6e172f29a45c59d5c30b2a7a697 events and turn off NIC interrupts while in the interrupt handler. This fixes the device timeouts seen with the VMware LANCE. - Relax the watchdog timer somewhat; don't enable it until the last packet is enqueued and if there is a TX interrupt but there are still outstanding ones reload the timer.

This version differs from HEAD in that if_le_ledma.c inlines lsi64854_enet_intr() from rev. 1.8 of sys/sparc64/sbus/lsi64854.c in le_dma_hwintr() in order to not break the API of the LSI64854 driver in RELENG_6.
