The TSO logic in the transmit path had some assumptions that
have been broken now that the kernel can send as much as 32kB
in a single skb->frag[.] entry, even on a system with 4kB pages.
This fixes the assumptions and allows the kernel to operate
as efficiently as possible with both SENDFILE and SEND.
In addition, the hardware limit of data contained in a descriptor is
changed to the next power of two below where it currently is in
order to align to a power of two value, preventing a single byte
of data in a descriptor.

The storm control features are not part of the hardware
and mistakenly were left in the code. Remove them as
they are not needed any more.

This patch contains the main driver header files, containing structures
and data types specific to the linux driver.
i40e_osdep.h contains some code that helps us adapt our OS agnostic code
to Linux.
