* tg3: Make tg3_alloc_rx_skb() a dst-only operationMatt Carlson2009-11-16
| | | | | | | | | | | | This patch removes the source index parameter of tg3_alloc_rx_skb(). A later patch will make it possible for the source and destination producer rings to be different. This patch opts to make tg3_alloc_rx_skb() a destination-only implementation and move the code sensitive to the difference elsewhere.

* tg3: Move napi_add calls below tg3_get_invariantsMatt Carlson2009-11-16
| | | | | | | | | | | | tg3_get_invariants(), among other things, discovers whether or not the device is MSI-X capable and how many interrupts it supports. This discovery needs to happen before registering NAPI instances with netdev. This patch moves the code block that calls napi_add later in tg3_init_one() so that tg3_get_invariants() has a chance to run first.

| | | | | | | | | | | | | | | Add support for Wake on LAN (WOL) reception and waking the device up from this signal via the ethtool interface. Currently we are only supporting the magic-packet variant of wakeup. WOL is enabled by specifying a second interrupt resource to the driver which indicates where the interrupt for the WOL is being signalled. This then enables the necessary ethtool calls to leave the device in a state to receive WOL frames when going into suspend.

* gianfar: Revive SKB recyclingAnton Vorontsov2009-11-11
| | | | | | | | | | | | | | | | | | Before calling gfar_clean_tx_ring() the driver grabs an irqsave spinlock, and then tries to recycle skbs. But since skb_recycle_check() returns 0 with IRQs disabled, we'll never recycle any skbs. It appears that gfar_clean_tx_ring() and gfar_start_xmit() are mostly idependent and can work in parallel, except when they modify num_txbdfree. So we can drop the lock from most sections and thus fix the skb recycling.

In an HT Beacon, HT stations use the "Operating Mode" field in the HT Information Element to determine whether or not to use protection. The Operating Mode field has 4 possible settings: 0-3: Mode 0: If all stations in the BSS are 20/40 MHz HT capable, or if the BSS is 20/40 MHz capable, or if all stations in the BSS are 20 MHz HT stations in a 20 MHz BSS Mode 1: used if there are non-HT stations or APs using the primary or secondary channels Mode 2: if only HT stations are associated in the BSS and at least one 20 MHz HT station is associated. Mode 3: used if one or more non-HT stations are associated in the BSS. When in operating modes 1 or 3, and the Use_Protection field is 1 in the Beacon's ERP IE, all HT transmissions must be protected using RTS/CTS or CTS-to-Self. By default, CTS-to-self is the preferred protection mechanism for less overhead and higher throughput; but using the full RTS/CTS will better protect the inner exchange from interference, especially in highly-congested environment. For 6000 series WIFI NIC, RTS/CTS protection mechanism is the recommended choice for HT traffic based on the HW design.
