  "message": "net: stmmac: fix TSO header length truncation\n\nstmmac_tso_xmit() stores the protocol header length returned by\nstmmac_tso_header_size() in a u8. stmmac_tso_valid_packet() admits\nheaders up to 1023 bytes, so a header longer than 255 bytes wraps modulo\n256 (486 becomes 230, 256 becomes 0).\n\nA TCP over IPv6 socket carrying a few hundred bytes of sticky\ndestination/hop-by-hop options makes skb_tcp_all_headers() exceed 255\nwhile staying below the 1023-byte limit, so such an skb reaches\nstmmac_tso_xmit().\n\nWiden proto_hdr_len to unsigned int, which is sufficient since the value\nis bounded by the hardware limit, and adjust the debug print specifier\naccordingly.\n\nFixes: 9edfa7dab811 (\"net: stmmac: enable TSO for IPv6\")\nSigned-off-by: Lorenzo Bianconi \u003clorenzo.bianconi@oss.qualcomm.com\u003e\nReviewed-by: Maxime Chevallier \u003cmaxime.chevallier@bootlin.com\u003e\nLink: https://patch.msgid.link/20260911-stmmac-fix-header-length-v1-1-8fc103334327@oss.qualcomm.com\nSigned-off-by: Jakub Kicinski \u003ckuba@kernel.org\u003e\n",
