net: enetc: use truesize as XDP RxQ info frag_size
[ Upstream commit f8e18abf183dbd636a8725532c7f5aa58957de84 ]
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.
