Message-Id: <20201031004918.463475-1-xie.he.0141@gmail.com> Date: Fri, 30 Oct 2020 17:49:13 -0700 From: Xie He <xie.he.0141@...il.com> To: Jakub Kicinski <kuba@...nel.org>, "David S. Miller" <davem@...emloft.net>, netdev@...r.kernel.org, linux-kernel@...r.kernel.org, Willem de Bruijn <willemdebruijn.kernel@...il.com>, Krzysztof Halasa <khc@...waw.pl> Cc: Xie He <xie.he.0141@...il.com> Subject: [PATCH net-next v6 0/5] net: hdlc_fr: Improve fr_rx and add support for any Ethertype The main purpose of this series is the last patch. The previous 4 patches are just code clean-ups so that the last patch will not make the code too messy. The patches must be applied in sequence. The receiving code of this driver doesn't support arbitrary Ethertype values. It only recognizes a few known Ethertypes when receiving and drops skbs with other Ethertypes. However, the standard document RFC 2427 allows Frame Relay to support any Ethertype values. This series adds support for this. Change from v5: Small fix to the commit messages. Change from v4: Drop the change related to stats.rx_dropped from the 1st patch. Switch the 3rd and 4th patch. Improve the commit message of the 4th patch by stating why only a 2-byte address field is accepted. Change from v3: Split the last patch into 2 patches. Improve the commit message of the 1st patch to explicitly state that the stats.rx_dropped count is also increased after "goto rx_error". Change from v2: Small fix to the commit messages. Change from v1: Small fix to the commit messages. Xie He (5): net: hdlc_fr: Simpify fr_rx by using "goto rx_drop" to drop frames net: hdlc_fr: Change the use of "dev" in fr_rx to make the code cleaner net: hdlc_fr: Do skb_reset_mac_header for skbs received on normal PVC devices net: hdlc_fr: Improve the initial checks when we receive an skb net: hdlc_fr: Add support for any Ethertype drivers/net/wan/hdlc_fr.c | 118 +++++++++++++++++++++++--------------- 1 file changed, 72 insertions(+), 46 deletions(-) -- 2.27.0
