ip_dev_find(net, addr) finds a device given an IPv4 source address and takes a reference on it. Introduce __ip_dev_find(), taking a third argument, to optionally take the device reference. Callers not asking the reference to be taken should be in an rcu_read_lock() protected section. Signed-off-by: NEric Dumazet <eric.dumazet@gmail.com> Signed-off-by: NDavid S.

For RPS, we create a kobject for each RX queue based on the number of queues passed to alloc_netdev_mq(). However, drivers generally do not determine the numbers of hardware queues to use until much later, so this usually represents the maximum number the driver may use and not the actual number in use. For TX queues, drivers can update the actual number using netif_set_real_num_tx_queues(). Add a corresponding function for RX queues, netif_set_real_num_rx_queues().

The ethtool utility does not set masks for flow parameters that are not specified, so if both value and mask are 0 then this must be treated as equivalent to a mask with all bits set.

由 Giuseppe CAVALLARO 提交于
The first version of the driver had hard-coded the logic for handling the checksum offloading. This was designed according to the chips included in the STM platforms where: o MAC10/100 supports no COE at all. o GMAC fully supports RX/TX COE. This is not good for other chip configurations where, for example, the mac10/100 supports the tx csum in HW or when the GMAC has no IPC. Thanks to Johannes Stezenbach; he provided me a first draft of this patch that only reviewed the IPC for the GMAC devices. This patch also helps on SPEAr platforms where the MAC10/100 can perform the TX csum in HW. Thanks to Deepak SIKRI for his support on this. In the end, GMAC devices for STM platforms have a bugged Jumbo frame support that needs to have the Tx COE disabled for oversized frames (due to limited buffer sizes). This information is also passed through the driver's platform structure.

commit ab95bfe0 (net: replace hooks in __netif_receive_skb) added rx_handler at wrong place, between two cache line aligned objects, creating a big hole (a full cache line) Move rx_handler and rx_handler_data before rx_queue, filling existing hole. Move master field in the cache line(s) used in receive path. This saves 64 bytes (or L1_CACHE_BYTES), and avoids two possible cache misses in receive path.
