# \[PATCH net\] octeontx2-pf: Set maximum queue size to 16K - From: Ratheesh Kannoth \ - Date: 2023-08-02 10:53:05 - List: netdev - Page: https://ratatoskr.run/netdev/2023/08/2288609 - Thread: https://ratatoskr.run/netdev/2023/08/2288609/t.md ```text page_pool_init() return error on requesting ring size > 32K. PF uses page pool for rx. octeon-tx2 Supported queue size are 16, 64, 256, 1K, 2K, 4K, 16K, 64K. If user try to configure larger ring size for rx, return error.
