2013-02-12gianfar: convert u64 status counters to atomic64_tPaul Gortmaker
While looking at some asm dump for an unrelated change, Eric noticed in the following stats count increment code: 50b8: 81 3c 01 f8 lwz r9,504(r28) 50bc: 81 5c 01 fc lwz r10,508(r28) 50c0: 31 4a 00 01 addic r10,r10,1 50c4: 7d 29 01 94 addze r9,r9 50c8: 91 3c 01 f8 stw r9,504(r28) 50cc: 91 5c 01 fc stw r10,508(r28) that a 64 bit counter was used on ppc-32 without sync and hence the "ethtool -S" output was racy. Here we convert all the values to use atomic64_t so that the output will always be consistent.

2013-02-12gianfar: remove largely unused gfar_stats structPaul Gortmaker
The gfar_stats struct is only used in copying out data via ethtool. It is declared as the extra stats, followed by the rmon stats. However, the rmon stats are never actually ever used in the driver; instead the rmon data is a u32 register read that is cast directly into the ethtool buf. It seems the only reason rmon is in the struct at all is to give the offset(s) at which it should be exported into the ethtool buffer. But note gfar_stats doesn't contain a gfar_extra_stats as a substruct -- instead it contains a u64 array of equal element count. This implicitly means we have two independent declarations of what gfar_extra_stats really is. Rather than have this duality, we already have defines which give us the offset directly, and hence do not need the struct at all. Further, since we know the extra_stats is unconditionally always present, we can write it out to the ethtool buf 1st, and then optionally write out the rmon data. There is no need for two independent loops, both of which are simply copying out the extra_stats to buf offset zero. This also helps pave the way towards allowing the extra stats fields to be converted to atomic64_t values, without having their types directly influencing the ethtool stats export code (gfar_fill_stats) that expects to deal with u64.

2013-02-04ethernet: Remove unnecessary alloc/OOM messages, alloc cleanupsJoe Perches
alloc failures already get standardized OOM messages and a dump_stack. Convert kzalloc's with multiplies to kcalloc. Convert kmalloc's with multiplies to kmalloc_array. Fix a few whitespace defects. Convert a constant 6 to ETH_ALEN. Use parentheses around sizeof. Convert vmalloc/memset to vzalloc. Remove now unused size variables.

2012-09-21gianfar: fix phc index build failureRichard Cochran
This patch fixes a build failure introduced in commit 66636287 ("gianfar: Support the get_ts_info ethtool method."). Not only was a global variable inconsistently named, but also it was not exported as it should have been. This fix is also needed in stable version 3.5.

2012-01-04gianfar: Reject out-of-range RX NFC locationsBen Hutchings
Currently the driver only uses location values to maintain an ordered list of filters. Make it reject location values >= MAX_FILER_IDX passed to the ETHTOOL_SRXCLSRLINS command, consistent with the range it reports for the ETHTOOL_GRXCLSRLALL command.

2011-09-16ethtool: Update ethtool_rxnfc::rule_cnt on return from ETHTOOL_GRXCLSRLALLBen Hutchings
A user-space process must use ETHTOOL_GRXCLSRLCNT to find the number of classification rules, then allocate a buffer of the right size, then use ETHTOOL_GRXCLSRLALL to fill the buffer. If some other process inserts or deletes a rule between those two operations, the user buffer might turn out to be the wrong size. If it's too small, the return value will be -EMSGSIZE. But if it's too large, there is no indication of this. Fix this by updating the rule_cnt field on return. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

2011-09-16ethtool: Clean up definitions of rule location arrays in RX NFCBen Hutchings
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.
