2015-09-23rocker: add FDB cleanup timerScott Feldman1-0/+42
Add a timer to each rocker switch to do FDB entry cleanup by ageing out expired entries. The timer scheduling algo is copied from the bridge driver, for the most part, to keep the firing of the timer to a minimum.

2015-09-23rocker: adding port ageing_time for ageing out FDB entriesScott Feldman1-0/+2
Follow-up patcheset will allow user to change ageing_time, but for now just hard-code it to a fixed value (the same value used as the default for the bridge driver).

2015-09-23rocker: store rocker_port in fdb key rather than pportScott Feldman1-4/+4
We'll need more info from rocker_port than just pport when we age out fdb entries, so store rocker_port rather than pport in each fdb entry. Signed-off-by: Scott Feldman <sfeldma@gmail.com> Acked-by: Jiri Pirko <jiri@resnulli.us> Signed-off-by: David S. Miller <davem@davemloft.net>

The entry is touched once when created, and touched again for each update. The touched time is used to calculate FDB entry age. Signed-off-by: Scott Feldman <sfeldma@gmail.com> Acked-by: Jiri Pirko <jiri@resnulli.us> Signed-off-by: David S. Miller <davem@davemloft.net>

Simplify and make consistent the current uses of inb/outb by using the newly introduced arcnet_<I/O> equivalents. o Add new #defines for register offsets There is an register offset, 8, that is unnamed and used as-is. o Remove old #defines that included the ioaddr o Remove obfuscating macros by expanding them in-place where appropriate o Create static inline com20020_set_subaddress for the SET_SUBADR macro There is an unused arcnet config entry CONFIGSA100_CT6001 which added a special #define BUS_ALIGN which was introduced but never used in fullhist git tree commit 22cfce4b82b0 ("[ARCNET]: Fixes.") in Nov 2004 for Linux v2.6.10. This BUS_ALIGN #define tries to allow 8 bit devices to work on a 16 bit bus by aligning addresses to 16 bit boundaries.

2015-09-21qeth: add layer 2 RX/TX checksum offloadingThomas Richter4-147/+285
Checksum offloading for send and receive is already supported for layer 3 (IP layer). This patch adds support for RX and TX hardware checksum offloading for layer 2 (MAC layer). The hardware calculates the checksum for IP UDP and TCP packets. This patch moves the hardware checksum offloading setup to the set of common functions in qeth_core_main.c. Layer 2 and layer 3 now simply call the same common functions. Also note that TX checksum offloading is always enabled. The device driver relies on the TCP/IP stack to make use of this feature.
