2011-12-19net: fix assignment of 0/1 to bool variables.Rusty Russell3-5/+5
DaveM said: Please, this kind of stuff rots forever and not using bool properly drives me crazy. Joe Perches <joe@perches.com> gave me the spatch script: @@ bool b; @@ -b = 0 +b = false @@ bool b; @@ -b = 1 +b = true I merely installed coccinelle, read the documentation and took credit.

2011-12-16ethtool: Define and apply a default policy for RX flow hash indirectionBen Hutchings1-1/+2
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.

2011-12-16ethtool: Centralise validation of ETHTOOL_{G, S}RXFHINDIR parametersBen Hutchings1-23/+12
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.

2011-12-04sfc: Use kcalloc instead of kzalloc to allocate arrayThomas Meyer3-4/+4
The advantage of kcalloc is, that will prevent integer overflows which could result from the multiplication of number of elements and size and it is also a bit nicer to read. The semantic patch that makes this change is available in https://lkml.org/lkml/2011/11/25/107 Signed-off-by: Thomas Meyer <thomas@m3y3r.de> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-10-19net: add skb frag size accessorsEric Dumazet2-5/+5

2011-09-16ethtool: Clean up definitions of rule location arrays in RX NFCBen Hutchings1-1/+1
Correct the description of ethtool_rxnfc::rule_locs; it is an array of currently used locations, not all possible valid locations. Add note that drivers must not use ethtool_rxnfc::rule_locs. The rule_locs argument to ethtool_ops::get_rxnfc is either NULL or a pointer to an array of u32, so change the parameter type accordingly.

2011-09-16sfc: Use correct fields of struct ethtool_coalesceBen Hutchings1-9/+27
An earlier developer misunderstood the meaning of the 'irq' fields and the driver did not support the standard fields. To avoid invalidating existing user documentation, we report and accept changes through either the standard or 'irq' fields. If both are changed at the same time, we prefer the standard field. Also explain why we don't currently use the 'max_frames' fields. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-09-16sfc: Correct reporting and validation of TX interrupt coalescingBen Hutchings3-34/+53
The reported TX IRQ moderation is generated in a completely crazy way. Make it simple and correct. When channels are shared between RX and TX, TX IRQ moderation must be the same as RX IRQ moderation, but must be specified as 0! Allow it to be either specified as the same, or left at its previous value in which case it will be quietly overridden.
