[PATCH 2/3] net/mlx5e: make VXLAN support conditional
From: Arnd Bergmann <hidden>
Date: 2016-05-04 12:32:13
Also in:
linux-rdma, lkml
Subsystem:
mellanox ethernet driver (mlx5e), mellanox mlx5 core vpi driver, networking drivers, the rest · Maintainers:
Saeed Mahameed, Tariq Toukan, Mark Bloch, Leon Romanovsky, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds
VXLAN can be disabled at compile-time or it can be a loadable module while mlx5 is built-in, which leads to a link error: drivers/net/built-in.o: In function `mlx5e_create_netdev': ntb_netdev.c:(.text+0x106de4): undefined reference to `vxlan_get_rx_port' This avoids the link error and makes the vxlan code optional, like the other ethernet drivers do as well. Signed-off-by: Arnd Bergmann <redacted> Link: https://patchwork.ozlabs.org/patch/589296/ Fixes: b3f63c3d5e2c ("net/mlx5e: Add netdev support for VXLAN tunneling") --- I sent it originally on Feb 26 2016, but misread Saeed Mahameed's reply as saying that he'd fix it up himself. The new version should address the original comment. --- drivers/net/ethernet/mellanox/mlx5/core/Kconfig | 7 +++++++ drivers/net/ethernet/mellanox/mlx5/core/Makefile | 4 +++- drivers/net/ethernet/mellanox/mlx5/core/en.h | 2 ++ drivers/net/ethernet/mellanox/mlx5/core/en_main.c | 4 ++++ drivers/net/ethernet/mellanox/mlx5/core/vxlan.h | 11 +++++++++-- 5 files changed, 25 insertions(+), 3 deletions(-)
