From 6a822d060c439bb700f2369767105f49135b94f8 Mon Sep 17 00:00:00 2001 From: Wey-Yi Guy Date: Tue, 13 Jul 2010 17:13:15 -0700 Subject: [PATCH] iwlwifi: add TLV to specify the size of phy calibration table Different devices have different size of phy calibration table; add new TLV to specify the size. If the TLV is not part of uCode header, the default table size will be used to make sure the backward compatibilities.
