# Update firmware detection code. This will now reliably detect

# Updates to the WEP configuration code. This adds support for shared

# cases) for changing the WEP keys without disabling the MAC port (thus
# triggering a reassociation by the firmware). This is needed by 802.1x

# sufficient to allow working 802.1x.

# [PATCH] skge driver (0.5)
#
# Version 0.5 of the rewrite of syskonnect gigabit ethernet driver.
#
# This version 0.5 has:
# * Build fixes for alpha and big endian
# * Power management, and wake on lan support
# * Better hardware error handling for flaky hw.
#
# Still not tested/debugged:
# * Genesis chip support -- does anyone still have one of
# these? May just drop it.
# * Suspend/resume
#
# Still not implemented:
# * Marvell Yukon2 88E8050
# * VLAN assist
#
# The patch should work on 2.6.8 or later, I am testing with 2.6.11-rc1.

# [PATCH] net/cosa: replace schedule_timeout() with msleep()
#
# Hi,
#
# Description: Use msleep() instead of schedule_timeout() to guarantee the task
# delays as expected. Also uses the set_current_state() macro instead of direct
# assignment in a pair of spots. I am still concerned about those sleeps, as
# TASK_INTERRUPTIBLE() is used without any checking for signals. Hence I used
# msleep() for the longer delay. Perhaps the 30 jiffy delay has not been
# updated for the larger HZ values and thus could be changed to msleep(300).

# [PATCH] 8139too: use iomap for pio/mmio
#
# Hi,
#
# This patch converts the 8139too driver to use the iomap infrastructure
# for PIO and MMIO instead of playing macro tricks. I also had to fix
# read_eeprom(), mdio_sync(), mdio_read(), and mdio_write() to not pass
# PIO base address to MMIO read() and write() functions. In addition,
# the patch adds proper __iomem annotations for the driver.
#
# Both modes, PIO and MMIO, were tested with a RealTel RTL8139 card on
# an x86 box. The 8129 support remains untested due to lack of
# hardware.

# [PATCH] Host AP: Do not bridge packets to unauthorized ports
#
# Fix inner-BSS bridge (ap_bridge_packets=1) not to bridge packets to
# unauthorized ports when IEEE 802.1X/WPA is used (i.e., require that
# the STA completes authentication before capturing packets in the inner
# bridge); previously, only association status was used and an attacker
# could have capture packets to any MAC address even without having
# proper credentials for using the network (although, the packets were
# dropped because the controlled port for the STA was unauthorized).

# [PATCH] Host AP: Prevent STAs from associating using AP address
#
# Prevent STAs from authenticating with AP address (i.e., spoofing AP
# MAC address). The inner bridge implementation intercepts packets
# before they are passed to Linux net stack, so using AP MAC address
# would prevent AP from seeing the packet properly.

# This patch (for wireless-2.6) should do this. I used separate buffers
# for RX and TX because they could be in theory called concurrently.
# Better to get this first working, but it might be worthwhile to consider
# the memory use at some point. This version uses 112 bytes of additional
# scratch buffers per key for CCMP.

+ Shared driver code for IEEE 802.11b wireless cards based on
+ Intersil Prism2/2.5/3 chipset. This driver supports so called
+ Host AP mode that allows the card to act as an IEEE 802.11
+ access point.
+
+ In addition, this includes generic IEEE 802.11 code, e.g., for
+ WEP/TKIP/CCMP encryption that can be shared with other drivers.
+
+ See <http://hostap.epitest.fi/> for more information about the
+ Host AP driver configuration and tools. This site includes
+ information and tools (hostapd and wpa_supplicant) for WPA/WPA2
+ support.
+
+ This option includes the base Host AP driver code that is shared by
+ different hardware models. You will also need to enable support for
+ PLX/PCI/CS version of the driver to actually use the driver.
+

+ *
+ * FIX:
+ * - there is currently no way of associating TX packets to correct wds device
+ * when TX Exc/OK event occurs, so all tx_packets and some
+ * tx_errors/tx_dropped are added to the main netdevice; using sw_support
+ * field in txdesc might be used to fix this (using Alloc event to increment
+ * tx_packets would need some further info in txfid table)
+ *
+ * Buffer Access Path (BAP) usage:
+ * Prism2 cards have two separate BAPs for accessing the card memory. These
+ * should allow concurrent access to two different frames and the driver
+ * previously used BAP0 for sending data and BAP1 for receiving data.
+ * However, there seems to be number of issues with concurrent access and at
+ * least one know hardware bug in using BAP0 and BAP1 concurrently with PCI
+ * Prism2.5. Therefore, the driver now only uses BAP0 for moving data between
+ * host and card memories. BAP0 accesses are protected with local->baplock
+ * (spin_lock_bh) to prevent concurrent use.

+In the event that fragmentation is required, the incoming payload is split into
+N parts of size ieee->fts. The first fragment contains the SNAP header and the
+remaining packets are just data.
+
+If encryption is enabled, each fragment payload size is reduced by enough space
+to add the prefix and postfix (IV and ICV totalling 8 bytes in the case of WEP)
+So if you have 1500 bytes of payload with ieee->fts set to 500 without
+encryption it will take 3 frames. With WEP it will take 4 frames as the
+payload of each frame is reduced to 492 bytes.
