Why do we have to permanently disable the data cache just because the
network driver is broken? USB is also broken, and probably other
drivers as well.
But this does not man we cannot use the data cache for other things.
Actually we WANT to be able to use it, so it is counter-productive to
disable it.
It should be sufficient to switch the cache off ("dc off") before
runnign any network related commands (and you want to make sure to
switch it on again afterwards).
Please PLEASE stop disabling cache support in the config files!
Rather invest efforts in fixing the broken drivers.
Thanks.
[In case it was not clear: This is a NAK.]
Best regards,
