[ Upstream commit e5ab564c9ebee77794842ca7d7476147b83d6a27 ]
The dst_cid and src_cid are 64 bits, therefore 64 bit accessors should be used, and in fact in virtio_transport_common.c only 64 bit accessors are used. Using 32 bit accessors for 64 bit values breaks big endian systems.
This patch fixes a wrong use of le32_to_cpu in virtio_transport_send_pkt.
Fixes: b9116823189e85ccf384 ("VSOCK: add loopback to virtio_transport")
