'RELENG_6_2_0_RELEASE'.
This commit was manufactured to restore the state of the 6.2-RELEASE image.
MFC: if_gem.c 1.31 + 1.35, if_gem_pci.c 1.20, if_gemvar.h 1.112005-10-05T22:08:17ZMarius Stroblmarius@FreeBSD.org2005-10-05T22:08:17Zurn:sha1:1a1b6619b554797f10433cc533122fdeab838363
- In gem_ioctl() move the call to ether_ioctl() to the default case of
the switch statement in order to make this driver more like other
Ethernet NIC drivers.
- In gem_attach() call gem_stop() in addition to gem_reset() to make
sure the chip actually is stopped and not just reset.
- In gem_stop() also stop the gem_rint_timeout() callout in case the
driver is compiled with GEM_RINT_TIMEOUT defined.
- Remove NOP spl*() calls and add locking (making gem(4) MPSAFE).
This MFC actually brings the RELENG_6 gem(4) in line with HEAD which
means that it additionally includes a comment update regarding the
IFF_OACTIVE -> IFF_DRV_OACTIVE rename which was part of if_gem.c 1.33
but missed in the respective MFC in 1.29.2.2.

Stop embedding struct ifnet at the top of driver softcs. Instead the2005-06-10T16:49:24ZBrooks Davisbrooks@FreeBSD.org2005-06-10T16:49:24Zurn:sha1:fc74a9f93a5fbc83262aa12084404ac953c854b5
struct ifnet or the layer 2 common structure it was embedded in have
been replaced with a struct ifnet pointer to be filled by a call to the
new function, if_alloc(). The layer 2 common structure is also allocated
via if_alloc() based on the interface type. It is hung off the new
struct ifnet member, if_l2com.
This change removes the size of these structures from the kernel ABI and
will allow us to better manage them as interfaces come and go.
Other changes of note:
- Struct arpcom is no longer referenced in normal interface code.
Instead the Ethernet address is accessed via the IFP2ENADDR() macro.
To enforce this ac_enaddr has been renamed to _ac_enaddr.
- The second argument to ether_ifattach is now always the mac address
from driver private storage rather than sometimes being ac_enaddr.

- Fix compilation without GEM_DEBUG.
- Do not #define GEM_DEBUG by default; it adds overhead (due to bzero()ing
RX space) and is not needed any more, since the driver is quite stable
now.
- Fix watchdog timeouts when failing to load TX packets.
- Do not forcibly limit the number of descriptors used for a packet to
GEM_NTXSEGS, by passing this number to bus_dma_tag_create(). There is
no requirement for a limit any lower than the total number of
available descriptors, and the present limit caused network problems
due to mbuf chains requiring more descriptors.
GEM_NTXSEGS is still used to estimate the interrupt window size, for
which we just need an estimate.

bus_dmamap_sync() overhaul:2003-01-21T17:17:01ZThomas Moestltmm@FreeBSD.org2003-01-21T17:17:01Zurn:sha1:b2d59f4234206fe3106aef373e6dd93075d1c314
- Remove NetBSD-style or-ed together BUS_DMASYNC operations, in some
cases relaxing the (intended) syncing operation a bit.
- Stop pretending that that we can sync part of a dmamap: replace the
GEM_CDTXSYNC and GEM_CDRXSYNC macros with GEM_CDSYNC to sync the
complete control map, and combine syncs wherever possible to avoid
the overhead.
- Sync all maps before unloading them.
- Remove a few syncs which should be unnecessary.
Add detach, shutdown, suspend and resume methods. The latter two are2003-01-08T20:12:45ZThomas Moestltmm@FreeBSD.org2003-01-08T20:12:45Zurn:sha1:cbbdf2367eb83eb3179661b14b34fd15f3e253df

- remove DPRINTF(), there is a CTR*() for any of them, and KTR is
far more useful to debug this driver.
- some cleanups; remove some unused code and definitions.

- Clean up how the local MAC address is programmed (NetBSD gem.c r1.13)
- Make the driver work on PowerMacs with gigabit interfaces
(NetBSD gem.c r1.14 and r1.15, gemreg.h r1.3 and r1.4, gemvar.h r1.6 and 1.7)
- Suppress RX_MAC interrutps regarding the FRAME_COUNT register.

- Fix receiver lockups. (NetBSD gem.c r1.18, gemvar.h r1.8)
