Some AES hardware acceleration instructions require each 16-byte round key to be aligned on a 16-byte boundary. Cipher contexts are byte arrays allocated by the caller and do not have any guaranteed alignment. Increase the AES context size to allow space for alignment padding, and align the context before use. Reduce the round count field from an unsigned int to a uint8_t, to minimise wasted space and to ensure that the resulting padded context size is itself reasonably aligned.

iPXE network bootloader
iPXE is the leading open source network boot firmware. It provides a full PXE implementation enhanced with additional features such as:
-
boot from a web server via HTTP or HTTPS,
-
boot from an iSCSI, FCoE, or AoE SAN,
-
control the boot process with a script,
You can use iPXE to replace the existing PXE ROM on your network card, or you can chainload into iPXE to obtain the features of iPXE without the hassle of reflashing.
iPXE is free, open-source software licensed under the GNU GPL (with some portions under GPL-compatible licences).
You can download the rolling release binaries (built from the latest commit), or use the most recent stable release.
