drivers: net: generalize napi_complete_done()

2017-01-30T20:10:42Z

napi_complete_done() allows to opt-in for gro_flush_timeout, added back in linux-3.19, commit 3b47d30396ba ("net: gro: add a per device gro flush timer") This allows for more efficient GRO aggregation without sacrifying latencies. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

2016-12-03T17:29:53Z

Couple conflicts resolved here: 1) In the MACB driver, a bug fix to properly initialize the RX tail pointer properly overlapped with some changes to support variable sized rings. 2) In XGBE we had a "CONFIG_PM" --> "CONFIG_PM_SLEEP" fix overlapping with a reorganization of the driver to support ACPI, OF, as well as PCI variants of the chip. 3) In 'net' we had several probe error path bug fixes to the stmmac driver, meanwhile a lot of this code was cleaned up and reorganized in 'net-next'. 4) The cls_flower classifier obtained a helper function in 'net-next' called __fl_delete() and this overlapped with Daniel Borkamann's bug fix to use RCU for object destruction in 'net'. It also overlapped with Jiri's change to guard the rhashtable_remove_fast() call with a check against tc_skip_sw(). 5) In mlx4, a revert bug fix in 'net' overlapped with some unrelated changes in 'net-next'. 6) In geneve, a stale header pointer after pskb_expand_head() bug fix in 'net' overlapped with a large reorganization of the same code in 'net-next'. Since the 'net-next' code no longer had the bug in question, there was nothing to do other than to simply take the 'net-next' hunks. Signed-off-by: David S. Miller

net: ethernet: altera: TSE: do not use tx queue lock in tx completion handler

2016-12-02T17:10:25Z

The driver already uses its private lock for synchronization between xmit and xmit completion handler making the additional use of the xmit_lock unnecessary. Furthermore the driver does not set NETIF_F_LLTX resulting in xmit to be called with the xmit_lock held and then taking the private lock while xmit completion handler does the reverse, first take the private lock, then the xmit_lock. Fix these issues by not taking the xmit_lock in the tx completion handler. Signed-off-by: Lino Sanfilippo Signed-off-by: David S. Miller

net: ethernet: altera: TSE: Remove unneeded dma sync for tx buffers

2016-12-02T17:10:24Z

An explicit dma sync for device directly after mapping as well as an explicit dma sync for cpu directly before unmapping is unnecessary and costly on the hotpath. So remove these calls. Signed-off-by: Lino Sanfilippo Signed-off-by: David S. Miller

net: ethernet: altera_tse: add support for SGMII PCS

2016-12-02T15:36:47Z

Add support for the (optional) SGMII PCS functionality of the Altera TSE MAC. If the phy-mode is set to 'sgmii' then we attempt to discover and initialise the PCS so that the MAC can communicate to the PHY. The PCS IP block provides a scratch register for testing presence of the PCS, which is mapped into one of the two MDIO spaces present in the MAC's register space. Once we have determined that the scratch register is functioning, we attempt to initialise the PCS to auto-negotiate an SGMII link with the PHY. There is no need to monitor or manage the SGMII link beyond this, since the normal PHY MDIO will then be used to monitor the media layer. The Altera TSE MAC has only one way in which it can be configured with an SGMII PCS, and as such, this patch only looks to the phy-mode to select whether or not to attempt to initialise the PCS registers. During initialisation, we report the PCS's equivalent of a PHY ID register. This can be parameterised during the IP instantiation and is often left as '0x00000000' which is not an error.
