Subject: [PATCH net-next 0/7] Remove three Sun net drivers

This series removes the Sun Cassini, LDOM vswitch and sunvnet drivers.

In a recent patch series that touched these drivers [1], it was suggested
that these drivers should be removed completely. git logs suggest that
there hasn't been any significant feature addition, improvement or fixes
to user-visible bugs in a while. A web search didn't indicate any recent
discussions or any evidence that there are users out there who care about
these drivers.

The idea behind putting out this series is to either establish that these
drivers are used and should be maintained, or remove them.

While the bulk of the code removal is in the networking s, and so
multiple subsystem lists are cc'd. Here's a quick breakdown:

  - patches 1/7 and 5/7 remove the drivers (netdev)
  - patch 2/7 removes Sun device IDs from pci_ids.h (linux-pci)
  - patch 3/7 changes ppc6xx_defconfig (linuxppc)
  - patch 4/7 changes MIPS mtx1_defconfig (linux-mips)
  - patch 6/7 removes the event tracing header sunvnet.h (linux-trace)
  - patch 7/7 changes sparc64_defconfig (sparclinux)

This series was compile tested as follows:

make O=b1 ARCH=mips CROSS_COMPILE=mips64-linux-gnu- defconfig
make -j$(nproc) O=b1 ARCH=mips CROSS_COMPILE=mips64-linux-gnu- all

make O=b2 ARCH=sparc64 CROSS_COMPILE=sparc64-linux-gnu- defconfig
make -j$(nproc) O=b2 ARCH=sparc64 CROSS_COMPILE=sparc64-linux-gnu- all

make O=b3 ARCH=powerpc CROSS_COMPILE=ppc64-linux-gnu- ppc6xx_defconfig
make -j$(nproc) O=b3 ARCH=powerpc CROSS_COMPILE=ppc64-linux-gnu- all
