Subject: [linuxppc-release] [PATCH 1/2] powerpc, e5500: add networking to
defconfig

Even though support for the p5020's on-chip ethernet is not yet upstream,
it is not appropriate to disable all networking support (including
loopback, unix domain sockets, external ethernet devices, etc) in the
defconfig.  The networking settings are taken from mpc85xx_smp_defconfig,
minus the drivers for ethernet devices not found on any current e5500 chip.

The other changes are the result of running "make savedefconfig".

Hi Scott,

I remember in previous testing that this option has a negative effect on performance.  Do we really need it to be enabled?

I didn't change this setting, it just moved due to running it through
savedefconfig.
