The type of all stat fields is u64, therefore when iterating over stat
fields in a stats struct, it makes sense to use an offset in 64 bit
resolution. Doing so allows us to drop some of the casting that is
currently used when referencing stats.

When using XDP every ingress packet is passed to an eBPF (xdp) program

This patchset introduces the following:
* add new admin command for supporting different queue size for Tx/Rx
* add support for Tx/Rx queues size modification through ethtool
* allow queues allocation backoff when low on memory
* update driver version

From: Sameeh Jubran
If there is not enough memory to allocate io queues the driver will
try to allocate smaller queues.
The backoff algorithm is as follows:
1. Try to allocate TX and RX and if successful.
1.1. return success
2. Divide by 2 the size of the larger of RX and TX queues (or both if

Currently ethtool -g shows the same size for current and max queue
sizes.
