From 61932ba59f5278e3f0c9fbded1a1af39ef89333f Mon Sep 17 00:00:00 2001 From: Arik Nemtsov Date: Mon, 6 Aug 2012 11:21:39 +0300 Subject: [PATCH] wlcore: spi: use private max-buf-size limit Limit SPI transmissions to the wl12xx max buffer size, as only 12xx was tested with SPI. This allows us to remove the global aggregation buffer constant.
