net: Support RX-ALL feature flag.

2012-02-24T09:42:07+00:00

This flag requests that network devices pass all
received frames up the stack, even ones with errors
such as invalid FCS (frame check sum).  This will
allow sniffers to see bad packets and perhaps
give the user some idea how to fix the problem.

net: Support RXFCS feature flag.

2012-02-24T09:19:59+00:00

When set on hardware that supports the feature,
this causes the Ethernet FCS to be appended
to the end of the skb.

Useful for sniffing packets.

ethtool: Null-terminate filename passed to ethtool_ops::flash_device

2012-02-01T19:47:17+00:00

The parameters for ETHTOOL_FLASHDEV include a filename, which ought to
be null-terminated.  Currently the only driver that implements
ethtool_ops::flash_device attempts to add a null terminator if
necessary, but does it wrongly.  Do it in the ethtool core instead.

ethtool: allow ETHTOOL_GSSET_INFO for users

2012-01-23T04:41:05+00:00

Allow ETHTOOL_GSSET_INFO ethtool ioctl() for unprivileged users.
ETHTOOL_GSTRINGS is already allowed, but is unusable without this one.

ethtool: Remove ethtool_ops::set_rx_ntuple operation

2012-01-04T19:10:28+00:00

All implementations have been converted to implement set_rxnfc
instead.

ethtool: Allow drivers to select RX NFC rule locations

2012-01-04T19:09:10+00:00

Define special location values for RX NFC that request the driver to
select the actual rule location.  This allows for implementation on
devices that use hash-based filter lookup, whereas currently the API is
more suited to devices with TCAM lookup or linear search.

In ethtool_set_rxnfc() and the compat wrapper ethtool_ioctl(), copy
the structure back to user-space after insertion so that the actual
location is returned.

ethtool: Define and apply a default policy for RX flow hash indirection

2011-12-16T18:53:18+00:00

All drivers that support modification of the RX flow hash indirection
table initialise it in the same way: RX rings are assigned to table
entries in rotation.  Make that default policy explicit by having them
call a ethtool_rxfh_indir_default() function.

In the ethtool core, add support for a zero size value for
ETHTOOL_SRXFHINDIR, which resets the table to this default.

ethtool: Centralise validation of ETHTOOL_{G, S}RXFHINDIR parameters

2011-12-16T18:52:47+00:00

Add a new ethtool operation (get_rxfh_indir_size) to get the
indirectional table size.  Use this to validate the user buffer size
before calling get_rxfh_indir or set_rxfh_indir.  Use get_rxnfc to get
the number of RX rings, and validate the contents of the new
indirection table before calling set_rxfh_indir.  Remove this
validation from drivers.

net: remove NETIF_F_NO_CSUM feature bit

2011-11-16T22:43:12+00:00

Only distinct use is checking if NETIF_F_NOCACHE_COPY should be
enabled by default. The check heuristics is altered a bit here,
so it hits other people than before. The default shouldn't be
trusted for performance-critical cases anyway.

For all other uses NETIF_F_NO_CSUM is equivalent to NETIF_F_HW_CSUM.
