    bnx2x: disable GSO where gso_size is too big for hardware · 8914a595
    Daniel Axtens authored
    If a bnx2x card is passed a GSO packet with a gso_size larger than
    ~9700 bytes, it will cause a firmware error that will bring the card
    down:
    
    bnx2x: [bnx2x_attn_int_deasserted3:4323(enP24p1s0f0)]MC assert!
    bnx2x: [bnx2x_mc_assert:720(enP24p1s0f0)]XSTORM_ASSERT_LIST_INDEX 0x2
    bnx2x: [bnx2x_mc_assert:736(enP24p1s0f0)]XSTORM_ASSERT_INDEX 0x0 = 0x00000000 0x25e43e47 0x00463e01 0x00010052
    bnx2x: [bnx2x_mc_assert:750(enP24p1s0f0)]Chip Revision: everest3, FW Version: 7_13_1
    ... (dump of values continues) ...
    
    Detect when the mac length of a GSO packet is greater than the maximum
    packet size (9700 bytes) and disable GSO.
