This patch adds the ethtool callbacks necessary to change the rss indirection table from userspace. Should the number of interrupts change (e.g. across a close / open call, or through a reset) and any one of the indirection table values fall out-of-range, the driver will reset the indirection table to a default layout. [Integrated many suggestions made by Ben Hutchings.] Changes since v3 * Removed TG3_FLAG_SUPPORT_MSIX checks at the start of tg3_get_rxfh_indir() and tg3_set_rxfh_indir(). Signed-off-by:

bnx2-mips-06-6.2.3 and bnx2-mips-09-6.2.1.b New firmware fixes iSCSI problems with some LeftHand targets that don't set TTT=0xffffffff for Data-In according to spec. Firmware generates exception warnings for this condition and becomes very slow. This is fixed by suppressing these warnings when using default error mask. Signed-off-by:

Lancer does not have HW registers to indicate the EQ causing the INTx interrupt. As a result EQE entries of one EQ may be consumed when interrupt is caused by another EQ. Fix this by arming CQs at the end of NAPI poll routine to regenerate the EQEs. Signed-off-by:

New FW can give clues to driver regarding default port type and whether or not we should default to link sensing on the port. 2 bits are added to QUERY_PORT command: 1. suggested_type: This bit gives a hint whether the default port type should be IB or Ethernet. The driver will use this hint in case the user didn't specify explicitly the link layer type he wants to set. 2. default_sense: If this bit is set, we would sense the port type on start-up and default the port to link sensing Signed-off-by:

For ConnectX3 devices, we allow link sensing only if FW explicitly reported it supports the feature. For older versions (ConnectX1 and 2), if the card supports both link layer types (Ethenet and Infiniband), link sensing is supported. Signed-off-by:

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. Partly-suggested-by:

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. Signed-off-by:

This initial DFS module provides basic functionality to deal with radar pulses reported by the Atheros DFS HW pulse detector. The reported data is evaluated and basic plausibility checks are performed to filter false pulses. Passing radar pulses are forwarded to pattern detectors which are not yet implemented.
