../tests/qtest/libqos/igb.c:106:5: runtime error: load of misaligned address
0x562040be8e33 for type 'uint32_t', which requires 4 byte alignment
Instead of straight casting the uint8_t array, we can use ldl_le_p and
lduw_l_p to assure the unaligned access working properly against
uint32_t and uint16_t.
