Xiao, Qi, Please take care of keeping all versions of the patch in the same thread, by using --in-reply-to with git-send-email. When a new version is sent, please delegate it to the right maintainer (Qi in this case) and set the old version as superseded in patchwork.
About the title, "fix" must be the first word, "hang issue" can be shortened with just "hang" ("issue" is never needed in a title, especially after "fix"). So it can be "net/e1000: fix i219 hang on reset/close" Thanks
