eth: bnxt: disable rx-copybreak by default
rx-copybreak requires an extra slab allocation. Since bnxt uses
page pool frags and HDS by default, the rx-copybreak doesn't
buy us anything. The extra pressure on slab causes overload
on pre-sheaves kernels on modern AMD platforms.
In synthetic testing on net-next this patch shows little difference
but I think copybreak is "obvious waste" at this point.
Default rx-copybreak threshold to 0 / disabled.
The "copybreak" defines are really the size bounds for the Rx header
buffer. Rename them.
