From: Jonas Bonn Date: Fri, 11 Jun 2010 02:47:34 +0000 (+0000) Subject: ethoc: calculate number of buffers in ethoc_probe X-Git-Tag: MMI-PSA29.97-13-9~23092^2~614 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c527f81475aaa18123eebe3d72a40a25d8e244af;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git ethoc: calculate number of buffers in ethoc_probe This moves the calculation of the number of transmission buffers to ethoc_probe where it more logically fits with the rest of the memory allocation code.
