*	tile on-chip network driver: sync up with latest fixes	Chris Metcalf	2011-03-10	1	-446/+515
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Combine the "command" and "completion" locks into a single lock, on each egress queue, to improve efficiency. Support the use of 4KB pages in the "egress queue". Delete the unused "duplicate ACK compression" code. Filter "bad" (i.e. truncated) packets. Avoid corrupting "dev->napi_list", by sequentializing modifications. Deregister for incoming packets during stop, to reduce unexpected interrupts. Also, encourage active NAPI loops to complete before we disable NAPI, which would otherwise crash. Free any pending completions after shutting down LEPP. Use a single, permanently registered, IRQ handler, to avoid situations in which the IRQ handler was firing after being freed, and ignore any "unexpected" interrupts. Drop egress packets, instead of spinning, if the hardware cannot keep up, or is disconnected. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
*	arch/tile: enhance existing finv_buffer_remote() routine	Chris Metcalf	2011-03-01	1	-2/+2
\| \| \| \| \| \| \| \| \| \| \|	It now takes an additional argument so it can be used to flush-and-invalidate pages that are cached using hash-for-home as well those that are cached with coherence point on a single cpu. This allows it to be used more widely for changing the coherence point of arbitrary pages when necessary. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
*	netdev: tilepro: Use is_unicast_ether_addr helper	Tobias Klauser	2011-01-14	1	-9/+1
\| \| \| \| \| \| \| \|	Use is_unicast_ether_addr from linux/etherdevice.h instead of custom macros. Signed-off-by: Tobias Klauser <tklauser@distanz.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
*	drivers/net/tile/: on-chip network drivers for the tile architecture	Chris Metcalf	2010-11-24	2	-0/+2416
	This change adds the first network driver for the tile architecture, supporting the on-chip XGBE and GBE shims. The infrastructure is present for the TILE-Gx networking drivers (another three source files in the new directory) but for now the the actual tilegx sources are waiting on releasing hardware to initial customers. Note that arch/tile/include/hv/* are "upstream" headers from the Tilera hypervisor and will probably benefit less from LKML review. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
