From: Ben Hutchings Date: Tue, 6 Sep 2011 13:49:12 +0000 (+0000) Subject: ethtool: Clean up definitions of rule location arrays in RX NFC X-Git-Tag: v3.2-rc1~129^2~272 X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?p=pandora-kernel.git;a=commitdiff_plain;h=815c7db5c809ea3d5735de3131ecdf758b0e14ff ethtool: Clean up definitions of rule location arrays in RX NFC 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.
