The NetReceive prototype gets a const buffer: typedef ssize_t (NetReceive)(NetClientState *, const uint8_t *, size_t); We already have the address_space_write() method to write a const buffer to an address space. Use it to avoid: hw/net/i82596.c: In function ‘i82596_receive’: hw/net/i82596.c:644:54: error: passing argument 4 of ‘address_space_rw’ discards ‘const’ qualifier from pointer target type [-Werror=discarded-qualifiers] This commit was produced with the included Coccinelle script scripts/coccinelle/exec_rw_const.
