+The value of 'tx_queue_size' is set to only 256 in the network device option on qemu 8.2.
+Description of problem:
+I have been using the 'tx_queue_size' value set to 1024 in the network device option on qemu 7.2 without any issues.\
+but when I upgrade to qemu 8.2 I got this error message (and also qemu 8.1) and I cannot use any value other than 256
+```
+qemu-system-x86_64: -device virtio-net-pci,mq=on,vectors=6,netdev=hostnet_34,id=dpdk_34,mac=F2:20:AF:40:12:65,bus=bridge,addr=0x7,page-per-vq=on,rx_queue_size=1024,tx_queue_size=1024,mrg_rxbuf=on,disable-legacy=on,disable-modern=off,host_mtu=1500,csum=on,guest_csum=on,host_tso4=on,host_tso6=on: Invalid tx_queue_size (= 1024), must be a power of 2 between 256 and 256
+```
+
+and I think virtqueue max size value has never changed from 1024.\

+Steps to reproduce:
+1. boot qemu-system-x86_64 on qemu 8.2 and network device option set tx_queue_size value over 256
+Additional information:
+- I'm using hardware vDPA offloading with mellanox NIC card.
