net: marvell: mvpp2: increase MTU limit when XDP enabled
[ Upstream commit 7b1b62bc1e6a7b2fd5ee7a4296268eb291d23aeb ]
Currently mvpp2_xdp_setup won't allow attaching XDP program if
mtu > ETH_DATA_LEN (1500).
The mvpp2_change_mtu on the other hand checks whether
MVPP2_RX_PKT_SIZE(mtu) > MVPP2_BM_LONG_PKT_SIZE.
These two checks are semantically different.
Moreover this limit can be increased to MVPP2_MAX_RX_BUF_SIZE, since in
mvpp2_rx we have
xdp.data = data + MVPP2_MH_SIZE + MVPP2_SKB_HEADROOM;
xdp.frame_sz = PAGE_SIZE;
Change the checks to check whether
mtu > MVPP2_MAX_RX_BUF_SIZE
