Sorry for that. During the last couple of years, maintenance of the project hasn't been easy, as I'm alone doing this. It may be that I miss some patches, or that having seen them don't find the time to address them. Please feel free to resend any such patches, and ping as much as necessary. Only if I explicitly reject a patch would mean I'm not interested in it, which will rarely happen. Also, please mind that I'm alone maintaining this, and may not have enough background to even understand the details of some new APIs, so it is encouraged to CC any other kernel maintainers or developers that may help reviewing your patches. Please have a look at the CONTRIBUTING file: Thanks, Alex >=20 > Thanks! >=20 >=20 > (specifically, Linux now permits you to assign the lowest, or "network"= , > address on a segment as a unicast address; it has for several years > permitted you to assign addresses from within 0/8; it has for many > years permitted you to assign addresses from within 240/4; and all of > these are also accepted as valid unicast destinations -- none of which > users would assume just from reading RFCs!) --=20 GPG key fingerprint: A9348594CE31283A826FBDD8D57633D441E25BB5 --------------JA9OTy9ChrsjU3A5SRMU9fjU-- --------------3zdGKO0aWNpiPF3NF6tALMAp Content-Type: application/pgp-signature; name="OpenPGP_signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="OpenPGP_signature" -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEE6jqH8KTroDDkXfJAnowa+77/2zIFAmQ3TroACgkQnowa+77/ 2zIMRA//ZbjNysWMVynY4qAnJf8JNQ/7GZaF1DMGA1acQOadKuOCqlIYFflAJAuT +A+mEfjGVEGcvAuuYSNZgcSj91/s10feTkQdqEpHHfPps69SqoynbM58haVvAdEN KF7n/ef2McZHfnpq3GzUaZ0OMSl4ESKC+pCDMpWqMKCT2f5/J1q7hVVONnUms3DA y+uEPjXag1Kjh0h6kq+7bTLnUV4KqHPQXlj0BOdNmC/heTipQH1Ro4kaRJvvLSs9 p4VPMNRoJQ3SHTzroRW0GtBw0qAGlBkr72nMWeVvaQIBYhDoaQTv6OFdOHPyTutS g2qiGAG4BmIPPwnmCtnwqKnQyJdDwktnqV2IsYLjv84P3+tCFTfXxhIWqHaOBYK8 xXAnaG7AHT789ROE4Kcm6vPwdk/H6OH4bGnHvcgYSSsaAMHZPbyA79is8QcrrVpu 6JzZoxuNdX8IKXx3qoHARzyk39w7vLhe3hPDMOByda48C7JvSbRz6qsgmPa6jeo0 pLFhxjQiCGnkdt3UBxbJ4VGhEezvC0vM+YmMKev+zo2TB03nEDiM6l3XPdeTtl0l rIzEmNZxblC1xgoaQPCLHQJfnFfsuOT6JBWHN0pd9ERA0ADCNE5KSaECN7pfW9H9 xGtb+e0N/1oQSKulf6g4qISAhymh724Ycs4DzeSjYKomuEds8JM= =06kP -----END PGP SIGNATURE----- --------------3zdGKO0aWNpiPF3NF6tALMAp--
