In this case assuming this goes into v3.7.5 this is being backported with special handling between 3.7.0 and 3.7.5 as follows onto compat. From: "Luis R. Rodriguez" <mcgrof@xxxxxxxxxxxxxxxx> Subject: [PATCH] compat: backport netdev_set_default_ethtool_ops() Stanislaw found that due to commit 2c60db03 by Eric Dumazet the wireless core was not assigning driver specific ethtool_ops. This was fixed by Stanislaw's commit d07d7507 which added netdev_set_default_ethtool_ops(). Since Eric's commit 2c60db03 is on v3.7-rc1 Stanislaw's fix is required down to v3.7 as well. The d07d7507 commit is currently present on v3.8-rc4 and is on its way to what we think may be v3.7.5. Because of this kernels older than v3.7.5 will require the full implementation while older kernels than v3.7.0 will require just assigning the ops passed only if netdev has no ops already set just as we used to have it implemented on cfg80211. mcgrof@frijol ~/linux-stable (git::linux-3.8.y)$ git describe --contains 2c60db v3.7-rc1~145^2~142 mcgrof@frijol ~/linux-stable (git::linux-3.8.y)$ git describe --contains d07d75 v3.8-rc4~29^2~4 ckmake results: 1 2.6.24 [ OK ] 2 2.6.25 [ OK ] 3 2.6.26 [ OK ] 4 2.6.27 [ OK ] 5 2.6.28 [ OK ] 6 2.6.29 [ OK ] 7 2.6.30 [ OK ] 8 2.6.31 [ OK ] 9 2.6.32 [ OK ] 10 2.6.33 [ OK ] 11 2.6.34 [ OK ] 12 2.6.35 [ OK ] 13 2.6.36 [ OK ] 14 2.6.37 [ OK ] 15 2.6.38 [ OK ] 16 2.6.39 [ OK ] 17 3.0.50 [ OK ] 18 3.1.10 [ OK ] 19 3.2.33 [ OK ] 20 3.3.8 [ OK ] 21 3.4.17 [ OK ] 22 3.5.7 [ OK ] 23 3.6.5 [ OK ] 24 3.7.0 [ OK ] real 0m34.791s user 11m38.572s sys 3m56.927s Signed-off-by: Luis R.
