- replace rtk_type member in rtk_softc which has chip types
with new rtk_quirk that represents quirks on each chip:
- RTKQ_8129 doesn't have internal MII (used in rtk(4))
- RTKQ_8139CPLUS has different register layout (for re(4))
- RTKQ_8169NONS (original 8169) requires some settings on init
- RTKQ_PCIE requires different settings in setmulti
so that we don't have to check each hwrev values or types everywhere
and newer variants will also work without changes if they don't
have other quirks
(sc_rev is unchenged for now for reference to the Realtek's driver)
- don't check hwrev register in re_pci_match() but check
only PCI_VENDER(), PCI_PRODUCT() and PCI_REVISION()
so that we no longer have to map pci space there
- add a new HWREV value for another 8168 variant
- try to map PCI mem space more properly
- remove (probably unneeded) ifp->if_baudrate initialization
Tested on a newer 8168 variant by Dennis den Brok on tech-kern,
and also tested on 8139 and 8169C on macppc, and 8139C+ on landisk
by me.
the Reaktek's driver, which are also used in FreeBSD.
Fixes RX FIFO overrun errors on my Duron 1300MHz PC.
(Note the configuration values for rtk(4) are not changed)
Also add some debug printf's in RX error case (disabled by default).
from RTK_ or rtk_ to RE_ or re_ for maintainability of these sources.
Eventually we should split these files (and struct rtk_softc) into
three elements, rtk(4) specific one, re(4) specific one, and a common
(register definitions, eeprom and multicast functions etc) part.
While here, add a couple of comments around weird definitions.
- move some driver specific definitions from rtl81x9reg.h to rtl81x9var.h
- move several macro where related structures are declared
- remove unused macro
- fix some comments
- unwrap some lines
- make DMA descripter members volatile
Now re(4) works on sgimips O2.
XXX: Still re(4) sometimes stalls on NFS load on sgimips,
XXX: but I'm not sure it's sgimips specific or not.
number of tx descriptors, number of rx descriptors, and number of mbufs.
- bump number of tx descriptors for rtl8169. 64 doesn't seem to be sufficient
when doing TSO.
- TSO support.
- fix some error handling.
- remove mysterious RTK_NTXSEGS and use more appropriate values
for bus_dmamap_create.
- if we need more than all of our tx descriptors in order to transmit a packet,
just drop it rather than retrying infinitely.
- Call bus_dmamap_sync(9) as appropriate.
- Leave only register declarations in rtl81x9reg.h and
split other stuff into rtl81x9var.h.
bus_dma(9) code mostly taken from thorpej's if_rtp.c.
