    tls: Remove redundant vars from tls record structure · 80ece6a0
    Vakul Garg authored
    Structure 'tls_rec' contains sg_aead_in and sg_aead_out which point
    to a aad_space and then chain scatterlists sg_plaintext_data,
    sg_encrypted_data respectively. Rather than using chained scatterlists
    for plaintext and encrypted data in aead_req, it is efficient to store
    aad_space in sg_encrypted_data and sg_plaintext_data itself in the
    first index and get rid of sg_aead_in, sg_aead_in and further chaining.
    This requires increasing size of sg_encrypted_data & sg_plaintext_data
    arrarys by 1 to accommodate entry for aad_space. The code which uses
    sg_encrypted_data and sg_plaintext_data has been modified to skip first
    index as it points to aad_space.
