So, RX-ALL can be one flag, another for RX-FCS, and the TX-CUSTOM-FCS can be a separate patch altogether?
That is the basic idea, yes.
Here are three patches. These were extracted manually from my big patchset. Where flags are defined, I left in the pktgen receive flag and the send-to-self flag from my larger patch set. If this is unacceptable, I can shuffle the flags around....
rx_all_ethtool.patch is the ethtool glue to turn on/off the RX-ALL and SAVE-FCS flags. I have not tested any of the ethtool-ops code branches as e100 and e1000 does not appear to use it.
rx_all_headers.patch should take care of defining the flags in if.h and netdevice.h
rx_all_e100.patch converts the e100 driver to support these features. I've ripped out the tx-custom-fcs code, but the rx-all and save-fcs code is there. The default behaviour is virtually identical, because while the old code was enabling receiving a lot of bad packets when in PROMISC mode, the check in e100_main rx code was throwing away anything that was not marked as good anyway...

However, one thing I want to make absolutely clear is that I do not want multiple ways to get the same information out of the kernel. We decided to build netlink into the kernel always because this means it is present in everyone's kernel. And therefore, we don't need to add another way to obtain the same config information already available via netlink. The existing cases where an
ioctl()style call exists to obtain the same info available via netlink is merely for compatability with older BSD tools. No new such things will be added.
Ok, I won't ask again. I attempted to get rid of all the 'ndstats' code from these patches. If some is still in there, it's an accident and I'll remove it.
Thanks,
Ben
