Re: [PATCH] net: liquidio: fix overflow in octeon_init_instr_queue()

Hello:

This patch was applied to netdev/net.git (main) by Jakub Kicinski kuba@kernel.org:

The expression `(conf->instr_type == 64) << iq_no` can overflow because `iq_no` may be as high as 64 (`CN23XX_MAX_RINGS_PER_PF`). Casting the operand to `u64` ensures correct 64-bit arithmetic.
