ethtool: Add support for configuring tx_push_buf_len
This attribute, which is part of ethtool's ring param configuration
allows the user to specify the maximum number of the packet's payload
that can be written directly to the device.
Example usage:
# ethtool -G [interface] tx-push-buf-len [number of bytes]
