o Header file cleanup.
o bus_dma(9) conversion.
- Removed all consumers of vtophys(9) and converted to use
bus_dma(9).
- 64bit DMA support was disabled because DP83821 is not capable
of handling the DMA request. 64bit DMA request on DP83820
requires different descriptor structures and it's hard to
dynamically change descriptor format at run time so I disabled
it. Note, this is the same behavior as previous one but
previously nge(4) didn't explicitly disable 64bit mode on
DP83820.
- Added Tx/Rx descriptor ring alignment requirements(8 bytes
alignment).
- Limit maximum number of Tx DMA segments to 16. In fact,
controller does not seem to have limitations on number of Tx
DMA segments but 16 should be enough for most cases and
m_collapse(9) will handle highly fragmented frames without
consuming a lot of CPU cycles.
- Added Rx buffer alignment requirements(8 bytes alignment). This
means driver should fixup received frames to align on 16bits
boundary on strict-alignment architectures.
- Nuked driver private data structure in descriptor ring.
- Added endianness support code in Tx/Rx descriptor access.
o Prefer faster memory mapped register access to I/O mapped access.
Added fall-back mechanism to use alternative register access.
The hardware supports both memory and I/O mapped access.
o Added suspend/resume methods but it wasn't tested as controller I
have does not support PCI PME.
o Removed swap argument in nge_read_eeprom() since endianness
should be handled after reading EEPROM.
o Implemented experimental 802.3x full-duplex flow-control. ATM
it was commented out but will be activated after we have generic
flow-control framework in mii(4) layer.
o Rearranged promiscuous mode settings and simplified logic.
o Always disable Rx filter prior to changing Rx filter functions as
indicated in DP83820/DP83821 datasheet.
o Added an explicit DELAY in timeout loop of nge_reset().
o Added a sysctl variable dev.nge.%d.int_holdoff to control
interrupt moderation. Valid ranges are 1 to 255(default 1) in
units of 100us. The actual delivery of interrupt would be delayed
based on the sysctl value. The interface has to be brought down
and up again before a change takes effect. With proper tuning
value, users do not need to resort to polling(4) anymore.
o Added ALTQ(4) support.
o Added missing IFCAP_VLAN_HWCSUM as nge(4) can offload Tx/Rx
checksum calculation on VLAN tagged frames as well as VLAN tag
insertion/stripping. Also add IFCAP_VLAN_MTU capability as nge(4)
can handle VLAN tagged oversized frames.
o Fixed media header length for VLAN.
o Rearranged nge_detach routine such that it's now used for general
clean-up routine.
o Enabled MWI.
o Accessing EEPROM takes very long time so read 6 bytes ethernet
address with one call instead of 3 separate accesses.
o Don't set if_mtu in device attach, it's already set in
ether_ifattach().
o Don't do any special things for TBI interface. Remove TBI
specific media handling in the driver and have gentbi(4) handle
it. Add glue code to read/write TBI PHY registers in miibus
method. This change removes a lot of PHY handling code in driver
and now its functionality is handled by mii(4).
o Alignment fixup code is now applied only for strict-alignment
architectures. Previously the code was applied for all
architectures except i386. With this change amd64 will get
instant Rx performance boost.
o When driver fails to allocate a new mbuf, update if_qdrops so
users can see what was wrong in Rx path.
o Added a workaround for a hardware bug which resulted in short
VLAN tagged frames(e.g. ARP) was rejected as if runt frame was
received. With this workaround nge(4) now accepts the short VLAN
tagged frame and nge(4) can take full advantage of hardware VLAN
tag stripping. I have no idea how this bug wasn't known so far,
without the workaround nge(4) may never work on VLAN
environments.
o Fixed Rx checksum offload logic such that it now honors active
interface capability configured with ifconfig(8).
o In nge_start()/nge_txencap(), always leave at least one free
descriptor as indicated in datasheet. Without this the hardware
would be confused with ring descriptor structure(e.g. no clue
for the end of descriptor ring).
o Removed dead-code that checks interrupts on PHY hardware. The
code was designed to detect link state changes but it was
disabled as driving nge_tick clock would break auto-negotiation
timer. This code is no longer needed as nge(4) now uses mii(4)
and link state change handling is done with mii callback.
o Rearranged ethernet address programming logic such that it works
on strict-alignment architectures.
o Added IFCAP_VLAN_HWTAGGING/IFCAP_VLAN_HWCSUM handler in
nge_ioctl() such that the functionality is configurable with
ifconfig(8). DP83820/DP83821 can do checksum offload for VLAN
tagged frames so enable Tx/Rx checksum offload for VLAN
interfaces.
o Simplified IFCAP_POLLING selection logic in nge_ioctl().
o Fixed module unload panic when bpf listeners are active.
o Tx/Rx descriptor ring address uses 64bit DMA address for
readability. High address part of DMA would be 0 as nge(4)
disabled 64bit DMA transfers so it's ok for DP83821.
o Removed volatile keyword in softc as bus_dmamap_sync(9) should
take care of this.
o Removed extra driver private structures in descriptor ring. These
extra elements are not part of descriptor structure. Embedding
private driver structure into descriptor ring is not good idea
as its size may be different on 32bit/64bit architectures.
o Added miibus_linkchg method handler to catch link state changes.
o Removed unneeded nge_ifmedia in softc. All TBI access is handled
in gentbi(4). There is no difference between TBI and non-TBI case
now.
o Removed "gigabit link up" message handling in nge_tick. Link
state change notification is already performed by mii(4) and
checking link state by accessing PHY registers in periodic timer
handler of driver is wrong. All link state and speed/duplex
monitoring should be handled in PHY driver.
o Use our own timer for watchdog instead of if_watchdog/if_timer
interface.
o Added hardware MAC statistics counter, users canget current MAC
statistics from dev.nge.%d.stats sysctl node(%d is unit number of
a device).
o Removed unused macros, NGE_LASTDESC, NGE_MODE, NGE_OWNDESC,
NGE_RXBYTES.
o Increased number of Tx/Rx descriptors from 128 to 256. From my
experience on gigabit ethernet controllers, number of descriptors
should be 256 or higher to get an optimal performance on gigabit
link.
o Increased jumbo frame length to 9022 bytes to cope with other
gigabit ethernet drivers. Experimentation shows no problems with
9022 bytes.
o Removed unused member variables in softc.
o Switched from bus_space_{read|write}_4 to bus_{read|write}_4.
o Added support for WOL.
