gianfar: rx parser

2011-07-15T23:00:20+00:00

Only let the rx parser be enabled if it is necessary (if VLAN extraction,
IP or TCP checksumming or the rx queue filer are enabled). Otherwise
disable it.

The new routine gfar_check_rx_parser_mode should be run after every
change on this features and will enable/disable the parser as necessary.

net: gianfar: convert to hw_features

2011-04-15T22:50:41+00:00

Note: I bet that gfar_set_features() don't really need a full reset.

gianfar: Clean up implementation of RX network flow classification

2011-04-11T20:28:43+00:00

This code was cribbed from niu, so gfar_set_hash_opts() begins by
converting the ethtool flow class code into a class code for Sun
Neptune hardware, then does the same thing again for the hardware it's
really dealing with.  It may also return -1 (-EPERM) for some
unhandled ethtool flow class codes.

Remove the useless code and definitions, and fix the error code.

gianfar: Fall back to software tcp/udp checksum on older controllers

2011-03-18T22:12:14+00:00

As specified by errata eTSEC49 of MPC8548 and errata eTSEC12 of MPC83xx,
older revisions of gianfar controllers will be unable to calculate a TCP/UDP
packet checksum for some alignments of the appropriate FCB. This patch checks
for FCB alignment on such controllers and falls back to software checksumming
if the alignment is known to be bad.

net: remove dev_txq_stats_fold()

2011-01-14T05:44:34+00:00

After recent changes, (percpu stats on vlan/tunnels...), we dont need
anymore per struct netdev_queue tx_bytes/tx_packets/tx_dropped counters.

Only remaining users are ixgbe, sch_teql, gianfar & macvlan :

1) ixgbe can be converted to use existing tx_ring counters.

2) macvlan incremented txq->tx_dropped, it can use the
dev->stats.tx_dropped counter.

3) sch_teql : almost revert ab35cd4b8f42 (Use net_device internal stats)
    Now we have ndo_get_stats64(), use it, even for "unsigned long"
fields (No need to bring back a struct net_device_stats)

4) gianfar adds a stats structure per tx queue to hold
tx_bytes/tx_packets

This removes a lockdep warning (and possible lockup) in rndis gadget,
calling dev_get_stats() from hard IRQ context.

of/device: Replace struct of_device with struct platform_device

2010-08-06T15:25:50+00:00

of_device is just an alias for platform_device, so remove it entirely.  Also
replace to_of_device() with to_platform_device() and update comment blocks.

This patch was initially generated from the following semantic patch, and then
edited by hand to pick up the bits that coccinelle didn't catch.

gianfar: Implement workaround for eTSEC-A002 erratum

2010-06-30T18:35:43+00:00

MPC8313ECE says:

"If the controller receives a 1- or 2-byte frame (such as an illegal
 runt packet or a packet with RX_ER asserted) before GRS is asserted
 and does not receive any other frames, the controller may fail to set
 GRSC even when the receive logic is completely idle. Any subsequent
 receive frame that is larger than two bytes will reset the state so
 the graceful stop can complete. A MAC receiver (Rx) reset will also
 reset the state."

This patch implements the proposed workaround:

"If IEVENT[GRSC] is still not set after the timeout, read the eTSEC
 register at offset 0xD1C. If bits 7-14 are the same as bits 23-30,
 the eTSEC Rx is assumed to be idle and the Rx can be safely reset.
 If the register fields are not equal, wait for another timeout
 period and check again."
