Doron Tsur 0b6e26ce89 net/mlx5_core: Fix trimming down IRQ number ... With several ConnectX-4 cards installed on a server, one may receive irqn > 255 from the kernel API, which we mistakenly trim to 8bit. This causes EQ creation failure with the following stack trace: [<ffffffff812a11f4>] dump_stack+0x48/0x64 [<ffffffff810ace21>] __setup_irq+0x3a1/0x4f0 [<ffffffff810ad7e0>] request_threaded_irq+0x120/0x180 [<ffffffffa0923660>] ? mlx5_eq_int+0x450/0x450 [mlx5_core] [<ffffffffa0922f64>] mlx5_create_map_eq+0x1e4/0x2b0 [mlx5_core] [<ffffffffa091de01>] alloc_comp_eqs+0xb1/0x180 [mlx5_core] [<ffffffffa091ea99>] mlx5_dev_init+0x5e9/0x6e0 [mlx5_core] [<ffffffffa091ec29>] init_one+0x99/0x1c0 [mlx5_core] [<ffffffff812e2afc>] local_pci_probe+0x4c/0xa0 Fixing it by changing of the irqn type from u8 to unsigned int to support values > 255 Fixes: 61d0e73e0a ('net/mlx5_core: Use the the real irqn in eq->irqn') Reported-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: Doron Tsur <doront@mellanox.com> Signed-off-by: Matan Barak <matanb@mellanox.com> Signed-off-by: David S.
