From: Alexander Duyck Date: Thu, 19 Aug 2010 13:40:31 +0000 (+0000) Subject: ixgbe: update all DESC_ADV macros to accept a ring pointer X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=31f05a2d875327ef133ac4b62261c4b875d1d10c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git ixgbe: update all DESC_ADV macros to accept a ring pointer All of the DESC_ADV macros are currently needing the pointers to be de-referenced before accessing the ring. Instead of having to add all of the asterisks it is easier to just update the macro to expect a pointer to the ring. Signed-off-by: Alexander Duyck Signed-off-by: Jeff Kirsher Signed-off-by: David S.
