In recent tests with new adapters, it was discovered that ARP packets were not being properly processed. This patch adds support for ARP packet headers to be passed to backing adapters, if necessary.

Introduce NETIF_F_GRO_HW feature flag for NICs that support hardware GRO. With this flag, we can now independently turn on or off hardware GRO when GRO is on. Previously, drivers were using NETIF_F_GRO to control hardware GRO and so it cannot be independently turned on or off without affecting GRO. Hardware GRO (just like GRO) guarantees that packets can be re-segmented by TSO/GSO to reconstruct the original packet stream. Logically, GRO_HW should depend on GRO since it a subset, but we will let individual drivers enforce this dependency as they see fit. Since NETIF_F_GRO is not propagated between upper and lower devices, NETIF_F_GRO_HW should follow suit since it is a subset of GRO. In other words, a lower device can independent have GRO/GRO_HW enabled or disabled and no feature propagation is required. This will preserve the current GRO behavior. This can be changed later if we decide to propagate GRO/ GRO_HW/RXCSUM from upper to lower devices.

In some case, we want to know how many sockets are in use in different _net_ namespaces. It's a key resource metric. This patch add a member in struct netns_core. This is a counter for socket-inuse in the _net_ namespace. The patch will add/sub counter in the sk_alloc, sk_clone_lock and __sk_free. This patch will not counter the socket created in kernel. It's not very useful for userspace to know how many kernel sockets we created. The main reasons for doing this are that: 1. When linux calls the 'do_exit' for process to exit, the functions 'exit_task_namespaces' and 'exit_task_work' will be called sequentially. 'exit_task_namespaces' may have destroyed the _net_ namespace, but 'sock_release' called in 'exit_task_work' may use the _net_ namespace if we counter the socket-inuse in sock_release. 2. socket and sock are in pair. More important, sock holds the _net_ namespace. We counter the socket-inuse in sock, for avoiding holding _net_ namespace again in socket. It's a easy way to maintain the code.

The current HNCDSC handler takes the status flag from the AEN packet and will update or change the current channel based on this flag and the current channel status. However the flag from the HNCDSC packet merely represents the host link state. While the state of the host interface is potentially interesting information it should not affect the state of the NCSI link. Indeed the NCSI specification makes no mention of any recommended action related to the host network controller driver state. Update the HNCDSC handler to record the host network driver status but take no other action.

The PHY performs just as well when left in its default configuration and it makes senses because this poke gets reset just after init. According to the documentation, all registers in the Analog/DSP bank are reset when there is a mode switch from 10BT to 100BT. The bank is also reset on power down and soft reset, so we will never see the value which may have been set by the bootloader. In the end, we have used the default configuration so far and there is no reason to change now. Remove CONFIG_A6 poke to make this clear.
