staging: rtl8188eu: Revert 4 commits breaking ARP
commit 66d32fdc upstream. Commit 2ba8444c ("staging:r8188eu: move IV/ICV trimming into decrypt() and also place it after rtl88eu_mon_recv_hook()") breaks ARP. After this commit ssh-ing to a laptop with r8188eu wifi no longer works if the machine connecting has never communicated with the laptop before. This is 100% reproducable using "arp -d <ipv4> && ssh <ipv4>" to ssh to a laptop with r8188eu wifi. This commit reverts 4 commits in total: 1. Commit 79650ffd ("staging:r8188eu: trim IV/ICV fields in validate_recv_data_frame()") This commit depends on 2 of the other commits being reverted. 2. Commit 02b19b4c ("staging:r8188eu: inline unprotect_frame() in mon_recv_decrypted_recv()") The inline code is wrong the un-inlined version contains: if (skb->len < hdr_len + iv_len + icv_len) return; ... Where as the inline-ed code introduced by this commit does: if (skb->len < hdr_len + iv_len + icv_len) { ... Note the same check, but now to actually continue doing ... instead of to not do it, so this commit is no good. 3. Commit d86e16da ("staging:r8188eu: use different mon_recv_decrypted() inside rtl88eu_mon_recv_hook() and rtl88eu_mon_xmit_hook().") This commit introduced a 1:1 copy of a function so that one of the 2 copies can be modified in the 2 commits we're already reverting. 4. Commit 2ba8444c ("staging:r8188eu: move IV/ICV trimming into decrypt() and also place it after rtl88eu_mon_recv_hook()") This is the commit actually breaking ARP. Note this commit is a straight-forward squash of the revert of these 4 commits, without any changes.
