Subject: net/mlx5e: XSK, Increase size for chunk_size param
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1047e14b44edecbbab02a86514a083b8db9fde4d;p=thirdparty%2Fkernel%2Flinux.git

net/mlx5e: XSK, Increase size for chunk_size param

When 64K pages are used, chunk_size can take the 64K value
which doesn't fit in u16. This results in overflows that
are detected in mlx5e_mpwrq_log_wqe_sz().

Increase the type to u32 to fix this.
