net: enetc: use truesize as XDP RxQ info frag_size

Browse source

[ Upstream commit f8e18abf18 ]

The only user of frag_size field in XDP RxQ info is
bpf_xdp_frags_increase_tail(). It clearly expects truesize instead of DMA
write size. Different assumptions in enetc driver configuration lead to
negative tailroom.

Set frag_size to the same value as frame_sz.
