From d2c5d77fff6ac0f43fc36f4fde020f726f773c1d Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Wed, 17 Apr 2013 15:00:52 +0300 Subject: Bluetooth: Add reading of all local feature pages With the introduction of CSA4 there is now also a features page number 2 available. This patch increments the maximum supported page number to 2 and adds code for reading all available pages (as long as we have support for them - indicated by HCI_MAX_PAGES).
